Belladonna!!
That is the obvious answer, Alex did not want to believe it but sadly that is reality.
He can handle Sandra and Belladonna perfectly alone, There will be no problem with him being able to manipulate them.
But if these two are together it's a nearly impossible job because these two are legit like fire and water, Both are standing opposite fractions with one another.
While Sandra is FL with her own female lead halo, Belladonna is villainess with her own villainess halo.
Both of them are natural enemies of one another and because of that both need completely different ways to deal with them.
He for Sandra goes with the stimulation route making her slowly get used to him being with other women, As FL has an immense inhuman level of possessiveness for her man, She likes to be one and only women in her man's life.
If he teased and stimulated her too much she would break and there is also the threat of her halo backlashing him for hurting heaven's loved one.
And then there is Belladonna, Who do not care about him being with other women. All she cares about is the fact she always would hold first place in her man's heart.
It's just she did not want only as lover to be first one in his heart, Rather the first person in his heart, No other being or thing can take that position away from her for which she can go to any extent.
Even if she had to kill all the populace of the world for her to be first in his heart, She would do it, Because she is a certified crazy bitch, A worse kinda Yandere.
So to tame someone like that, He has to be always in power over her, Never give her any chance to take the power and for that use all kinda moderate amounts of measures and stimulants to deal with the threat.
'What to do? What to do? There has to be a way right? Right?!!!'
Alex for the first time coming to this world felt this much of panic, All this work can be destroyed in this instance if he made one wrong move, Be it from Sandra or Belladonna.

Gears in his head started to spin all kinds of plans he could use here come to his mind but newly all of them were rejected by him outright as one plan is only good for one of them not two of them together.
It's the conundrum of the problem, He needs to stimulate Belladonna for her to be on the leash and not go around in a killing spree but he can not stimulate Sandra because she would break under it or just trigger her passive of FL.
'Should I just pretend to be unconscious? It would stall enough time that Belladonna had to retreat.'
Alex thought of the worst plan for him, That is to just pretend to be dead and hope the danger would go away, He is not the one who likes to be at mercy of odds.
Yeah because Belladonna is not here she can't indefinitely use her puppet to this from this long distance, she had to retreat after a while but that is a thing, he didn't know the time limit of hers.
It may be 1 hour or 1 day, And the plan of falling unconscious would have even worked if not for him inviting others to his dormitory.
If he did not reach there, He would create another trouble while avoiding one.
'Maybe…I can do that but it's risky.'
Amidst the chaos of ideas a new plan popped up which caught his attention. This is something he has never done before but this plan has the most potential to be effective against Both of them.
The fact that both of the women are not in front of him which before was a problem with this plan can be used as an advantage against them.
[Ding! World choice is detected…
Please choose the following options…
•[1] You are in grim danger, Try to save your ass.

As the trusty system is when it detected there were world choices here, It quickly jumped up and released the task with quite good-looking rewards. If the situation was not this severe Alex would have stopped to appreciate such a reward.
Because even though he doesn't know the powers of it, By the names of it they are quite powerful things.
'System do you want me to see dead? Because 2nd task is how I would end up dead.'
But Alex after seeing the task of 2nd option could not help but to sincerely ask the system what he wants, After all he is here struggling to salvage the situation and it wants me to do the impossible.
Even if those two were not present here at the same time, This task was nearly impossible to do in this short time without much preparation but now they are here, It is a legit impossible task.
If he is food enough to attempt this thing, he is surely going to get hacked to death with a knife by any one of them, As the thing they share in common is their twisted worldview and excessive passion for their man.
Alex is not stupid not desperate enough to try attempting to do the 2nd task. After all, he loves being alive.
[Ding! Host it's upto you to decide what you want to do, I just have possible options for it, Also the 2nd task is indeed nearly impossible so because of that system can increase the rewards with risk assessm-]
'Okay then, Accept the 1st and 2nd option quickly, We can't waste time."
System started answering Alex but the moment it finished speaking that reward is worth the risk of the task which has always been the case just not said out loud, Alex did not waste any time accepting the task as cold glint flashed in his eyes.
[...]
The system was speechless. How could one person change their nature this quickly? At one moment he was being panic next he was complaining about unfairness and then right after that eagerly accepted the same task?
It could not under this human thing at all, Thankfully it doesn't need to, So it just silently registers the choice of Alex and becomes silent.
'I don't need to use words against Belladonna, My action and her searching my body would be enough for her, As for Sandra, The ace of all cards, The Victim card would be sufficient.'
Alex with newfound passion started making plans to take down both of the women in one swoop, the fear he had for them vanished the moment he heard that reward will be worth it.
Right now he is even ready to use underhand methods against them, The tricks bottom of his box to make both female lead and villainess front of his will.

Alex concocted a devious plan in his head as he looked towards the door of the ward with that all-knowing look in his eyes, He finally decided to let loose his inner man.
"*Cough* Leave me both of you, I do not deserve your love and care, I am a loose man who deserves to be left on the streets, That is where I belong."
Alex stands up and shoves both Liza and Grace away from him, Starting his melodrama of showing hate and disgust for one's own self.
He rubbed his hand off as he was trying to dust the filth of it but he couldn't, So he kept rubbing till his hands became red from the friction from the power and force he was putting behind it.
But he didn't care, just tried to clean himself by rubbing not only his hand but his whole body in utter disgust, wanting to get rid of this dirty flesh and skin which making him nauseous.
"What you saying, Stop it, Stop hurting yourself, Alex."
"Yeah, How can the heirs of the Winchester family say that? Come to your senses, Alex."
Both Liza and Grace seeing this sudden change in Alex were taken aback, They didn't understand what had gotten in Alex.
The Alex they know should be right now teasing them asking if they wanna join him with that charming evil smirk.
Grace has quite some experience with that and she was even ready to respond positively to Alex if he asked but this reaction of his was truly unexpected.
Her heart seeing him this desperate broke into a million pieces, Her eyes became moist with tears she was holding back not wanting to show her weak side in the time of need of Alex.
She hardened her heart and quickly caught his hand which did not stop scratching his skin waiting to peel it outright from his flesh.

When she caught his hand she saw the bleeding traces of nail scratches left on his body and hands, even the nail had a few pieces of skin stuck on it.
Grace really wanted to hug him tightly in her arms and burst out crying as if the wounds were not on his body but on hers, Rather it would have been hurt less if it was on her body than seeing them on her beloved.
She desperately wanted to help him but didn't know how to, This was all new to her, Her tsundere Alex never acted out this way.
Liza though so badly wanted to console him, She was busy keeping an eye on his vitals as his spiritual power was already fluctuating, There was a high risk of it collapsing under the emotional instability of Alex.
"Hurting myself? It's not that big of a deal. Even if I tried my best to harm myself, I would be fine, I am heir of the Winchester family after all. Forget about that, Tell me why do you still care about me?"
Alex looked at Grace hearing her plea to stop from harming himself with a smile filled with heart-wrenching pain making him look like he was about to laugh hysterically and cry miserably at the same time but he was holding himself back from doing neither of it.
"Do you have any idea what I did before you came here? If you know you would definitely hate me, So go away, leave me alone, I can't bear to be hated by you."
Alex stopped his moment and looked dead in Grace's eye with a blank look and spoke in a lifeless tone. He felt like she gave up on everything, Nothing mattered to him now, he was just done with it.
*Bang*
Grace felt like someone just slammed the hammer on her heart, The tears she was so tirelessly trying to hold back could not be also to stopped breaking the bounds of her eyes flowing endlessly from her delicate cheeks.
She didn't know what to do, So she did what her heart felt like doing it, She opened her arms wide and took him in a warm soft embrace, making him press on her softness.
Alex tried to resist it at first but maybe feeling her warmth he gave up his struggle, and lay in her embrace which protected him from outside elements for him to be vulnerable here like a sanctuary just made for him.
"Don't say that, I don't know what is happening with you but you are not allowed to harm yourself. You get that thought in your head, I don't know to what extent I have right over you or have my place in your heart but I know I have some.
So your body does not belong to only yourself, I too have a right over it and using that right I forbid you from harming which is mine, Do you understand? You as a whole are mine through heart and body."

Grace tightening her hug trying to give as much as comfort to him as possible and then said the words she only used to say in her mind but never had the courage to say to him.
But this time she didn't know where that unseen courage came from, She spoke up in her stern tone which was previously impossible for her to do to Alex, This is something even liquid courage could have not brought out of her.
"*Chuckle* You know just before you come here, I slept- No, I fucked Aunty till she passed out in exhaustion, Now can you still say a man like belonged to you?"
Alex's body tightened in her arms, It was an unusually warm embrace. He cuddled in her arms before saying it or Grace tried to get a reaction from her.
Get her to yell at him, curse him or even leave him to be here alone disgusted hearing such a vile thing being spoken of about her mother which might be what Alex was looking for.
"I know, I heard everything, So what about it? We already had a deal, didn't we? You just made the difficult task of convincing my mother to sleep with you rather easy, And for that, I should thank you,
After all, I really had no idea how I should bring up that topic with my mother, I am honoured to have such a considerate boyfr-man."
But unlike everyone expected, Grace did not react at all, she just gave a heartfelt smile, A genuine heartfelt smile not a pretended one and answered him.
They already had that deal. When Gloria means her mother recovers, She would help Alex get into the pants of her mother, Which sounds bad but she was willing to do it for Alex.
Yeah, there was a jealousy factor of Alia taking his first time but it was only a small portion. She really wanted to make Alex happy and for that, she was willing to do anything.
"...You are hopeless, Do you know that? Women should have some spine."
Alex was left speechless by her answer but later spoke such words under his breath while warping his hands around her slender waist also taking her in his hug.
'There he is, My big tsundere.'
The moment Grade heard those words rather than being embarrassed she smiled, As this is the Alex she knows means she is actually able to ask him what was all that about without working about triggering him.
After all, she spent years with this Alex, She knew all his triggers what to say and what not to say, So she was quite happy.
"Interesting."
A shadow hidden in the dark spoke in a hoarse voice as it saw the changes in Alex the moment he hugged Grace.

The figure in the dark was really taken aback when she saw his wounds start to heal at a speed visible to make eyes, In no time his wound healed and became as good as new, As if it was never damaged.
She who spent as much time in the supernatural world had not seen something like this before. Yeah there are healing superpowers but Alex already has fire-related superpowers, So this is clearly not because of his superpowers.
And even if she considers that his fire is somehow related to his healing ability, It still does not make sense by how his healing power works.
She was monitoring his every move including his internal ones, So she would have been the first to notice if his superpower had been triggered as all superpowers need spiritual energy to work.
But it did not happen, rather nothing had happened until he hugged that damn guy woman who has the audacity to call Alex belongs to her, Who she would have to deal with later.
Anyway, What is important thing is that, the moment Alex hugged her his wound started to heal, And the fact is that she was not able to detect how his wound got healed.
There was just one flash of unknown energy and he was good as new. It happened so fast that others might not even notice that all his wounds had been healed.
She was fascinated by that, If not for the bounding of this vessel, She really wanted to drag Alex away from here and test what made that happen
*Growl*
Xiao Bai sensed the presence again of that person in the dark, She suddenly became territorial as she didn't want another unknown S-Rank force around Alex, It was not good for his safety.
'Calm down girl, Don't attack, just stay put as I said before.'
Alex, seeing what he this fluff ball wanted to do, quickly spoke to her through their telepathic contract connection.

Of course, he did not forget about her like a rookie. The moment he decided on the plan, He alerted her that no matter what he did or acted, She should not react.
After all, if he hadn't warned her beforehand, She seeing Alex going through "anguish" would have snapped out and gone on her own rampage to hunt and kill the person who hurt him.
He knows what she is capable of even if that power hides beneath her vast cuteness, So he planned all out.
And now he was sure he had gotten the attention of his dear fiancee, Now he wanted to put a target on Sandra.
"So now you are ready to tell me what's just happened?"
Grace not knowing what is going through the head of her man she thinks can never do any wrong asked in her sweet soul soothing tone careful of not to trigger his emotions again.
Liza on the other hand was too busy monitoring his vitals through her special technique, Though she wanted to be one who comforted him in his time of need but this was more important.
So she let Grace do the calming thing as she looks like she knew how to handle the situation while she here does what she is good at and that is to make sure he would not die.
Alex on the other hand could not help but to love more of this helpless girl, Everytime he wants something, She would do it without him asking as if there is a telepathic connection between them.
Just like now, How badly he was waiting for the right opportunity to strike and here comes his knight in shining armour for rescue.
Now that the opportunity is given, He decided to fully is going all out.
"...I hate myself that I am not able to control my urges, I loathe myself that I even enjoy doing it."
Alex took a moment to gather his thoughts and then tightening his embrace on her for fearing that she would leave him after hearing his answer.
His light tone has an obvious fear of rejection and abandonment, He is like a lost puppy clinging onto her not wanting to be left alone here fearing his ownself isolation.

"Why? What do you mean? Can you tell me, Alex? You can tell me Here we even have a doctor. Who can help us better understand this didn't it?"
Grace of course felt his micro action and felt she would cry once again from the overwhelming sense of grief and sadness by the thought of Alex going through distress and she couldn't do anything other than just sit here and listen.
But she did not show it on her face. She also became bold and hugged him as tightly as she comfortably could, making sure to let him know her action and that she would not abandon him before asking him to tell her the reason behind this sudden outburst.
She had an idea about it but it was not the issue before, So she was not completely sure if that might be the reason behind his outburst or if there was something else behind it.
There are too many such questions, So rather than making assumptions, She does what she feels is right and asks Alex about it, Which actually is a big taboo here to ask a man why he is crying about.
Women should just somehow figure out why their man is crying without asking them, Is that too much to ask?
Anyway, thankfully Alex is actually not like other men. He adored that she asked him, So he could start his melodrama and get the title of being king of melodrama.
"I…I just was able to control it, Grace. Before in my teenage years, I still had slightly weird feelings about women but I was able to control it. Yeah, it used to hurt but I got used to that pain."
Alex once again went through word by word what he wanted to say before he said it to Grace in not so not-so-light tone, Rather he spoke up in a loud hurried tone appearing as to speak all this up as soon as possible to Grace.
"It was fine till a few days ago, But after I had sex with Alia, I became just out of control, I could not control myself, Everytime I look at the woman, I wanted to bang her. The thought before would have disgusted me now makes me more excited."
Alex spoke these words loud and clear hugging tightly to Grace as if he was not sure Grace would react positively to his words,
Liza on the other hand when she heard started to go through multiple reasons for what Alex was talking about, many medical conditions came up in her mind that matched the description of Alex's problem but she still needed more information about it before she could give her verdict.
"Having sex with beautiful women like you makes me feel good. The pain that has always been there like an uninvited guest, After the sex even if for a little bit of time goes away, And I don't lie to you but I might be addicted to the sex."
Alex said these things with a straight face without any shame or hesitation, Like this was not the main reason why he reacted the way he did.
Which not only going to also virtual single others that this is not a bad thing but they would also be going to pay attention to his next point more thinking the reason would be the next thing.
"Maybe that is why I lost control over my actions, I didn't want to do that with Aunty Gloria this soon but after I used a Fairly blessing skill on her to heal her completely, I felt black front of my eyes.
My body felt tool weak to even stand, There is a burning feeling as if my body is set on fire and then I saw aunty wake up, After that my instincts took over, I was aware of what I was doing but wasn't able to stop myself from tarnishing aunty's image that way."
Alex prayed in his heart before he uttered these words. The result of these words is going to decide whether or not he will be successful in his task.
