Going back to the top floor, Natsu learned something from Rias which further increased his happiness.
Turns out that after 25 different monsters of the same species appear inside a Dungeon, you could buy those monsters without having to buy the ordinary monster and hope for them to evolve.
Now with double the happiness, Natsu took his time in enjoying a steamy hot bath to get rid of the swear and dirt on him, with Grayfia and Amaterasu like always.
Only, there was a small difference this time.
Just as Natsu was about to leave, Rias entered the room with a towel wrapped around her.
"Could the two of you leave, there's something I need to talk with my darling."
Grayfia directly got up to leave, while Amaterasu who felt curious hesitated for a split second before leaving with Grayfia.
However, after the two of them left the bathroom and closed the door behind them, they didn't go any further and instead pressed their ears against the door in hopes of hearing what was happening on the inside.
Closing her eyes to build up her confidence, Rias slowly opened them and removed the towel wrapped around her body and revealed her completely naked body to Natsu for the first time ever.
"What do I owe this pleasure to, Rias?"
"I miss you, darling."
"Huh? Am I not right here?"
Gritting her teeth, Rias said, "That's not what I meant."
"I want you to pay attention to me, darling!"
"You're always hanging around other women!"
"In the beginning, it was only that one human. But now you're hugging the maid to sleep as well!"
Not knowing what to say Natsu was starting to feel a little awkward, when Rias continued speaking on her own.
"Also, why is every woman inside your Dungeons a beauty?!!"
"And you even summoned a sexy Elf as your hero!"
"You... You've been putting me, the first woman who was by your side from the beginning aside, darling!"
"Rias... You... "
Snorting towards Natsu who seemed to be uncertain of what to say, Rias eyes which were wet almost burst out into tears.
"Humph! Even now after I've shared my real feelings, you aren't reacting in the slightest!!!"
Hearing those words Natsu's mouth fell wide open as he truly didn't know if he should laugh or cry.
Putting aside Rias who suddenly spoke so much, what could someone like Natsu who wasn't experienced in such situations do?
"Rias."
"What?"
"I..."
"You?"
Sighing from how Rias wasn't even giving him time to think, Natsu beckoned her closer with his hand and invited her inside the tub.
"Humph! As perverted as always! Is sex all that's on your mind?"
"Sigh... Just get in Rias."
Not saying anything else, Rias desperately hid the blush which was threatening to appear in her face at any time and stepped inside the tub.
But, before she could sit opposite to Natsu, he held her body and pulled it into his embrace and slid into the warmth of the water.
Not letting go of Rias who was weakly trying to resist, Natsu finally asked, "Have you calmed down?"
Meekly nodding her head, Rias declined to answer and almost made Natsu chuckle.
Unfortunately, while he wanted to enjoy the situation, Natsu who was dealing with unchartered territories, didn't have the time to do so.
Thus, a long silence appeared which made Natsu and Rias feel awkward and not know what to say.
Finally just as Rias was starting to feel that she made a stupid decision by telling Natsu about how she felt, Natsu started patting her back and said, "I'm sorry."
"Huh?"
"I'm sorry I haven't been there by your side."
Just like Natsu said, even after the mysterious voice spoke and told him to share his thoughts with a woman, especially after that, Natsu unconsciously placed a little distance between him and Rias.
It wasn't because he didn't want to share his feelings, but he was afraid and didn't know how to start.
"But you weren't there by my side either!"
"What?!"
Feeling aggrieved, Rias placed her hands on Natsu's chest and propelled herself upwards.
"What do you mean I wasn't there by your side?! What do you expect me to do when you were the hugging the maid to sleep??!!!"
"That's not what I meant, Rias."
"Then what did you mean? You wanted me to join or see you when you were having sex with that human???!!!"
"Listen to wha... "
Stopping in middle, Natsu sighed for the umpteenth time and completely forgot about the happiness he obtained from learning about the evolution of one of his Goblins.
"You're right. I'm sorry."
Smiling happily from hearing those words, Rias went back to hugging Natsu and enjoying the bath together.
Sighing inside, after having gone through this Natsu said to himself that he would never bother fighting a woman with his words.
If he won, she'd call him petty for fighting with a woman. And if he lost, she'd look towards him as if he was a loser.
Either way, regardless of what happens, Natsu definitely wouldn't be in a favourable situation.
Therefore, Natsu decided that from the next time onwards he would just gracefully give in and take the easy way out, instead of having a meaningless quarrel.
Of course, if it was in a serious topic, Natsu definitely wouldn't give in.
But when it was on stupid things topics like the one which they were talking about right now, it was best to just go along with what the woman wanted.
After all, a true gentleman like Natsu would never be petty enough to fight against his own women for meaningless things like pride.
