The same day around seven in the evening—
When Regis returned to the main room of the special training room, what greeted him is Reena, sitting on one corner of the room, in a very bad mood. Her face is clearly worse than what she has earlier form the Academy Director's office.
The special training that Manaria lent to Regis was a very spacious room with a few sub-rooms, a shower room and a toilet inside. Considering that it was built for training purposes, inside the sub-rooms are beds for the trainee to rest at which is almost the same as their dormitory room.
"Oh, you already finish inspecting the rooms, Reena? What's with that face? Did you wake up on the wrong side of your bed?"
Regis nonchalantly walked towards her and asked the little girl who's in the bad mood. He even tried to joke a little bit which expectedly made an adverse effect.
"Big Brother!!! Why did big brother bring that princess here?! And…—Why is that girl sleeping on big brother bed?!" asked Reena angrily as she stands up and stares up at Regis. Just form a single glance; anyone will immediately know that she's throwing a fit of temper.
Turning back the time around half an hour before this scene...
After leaving the director's office, Regis quickly brought Arias in the special training room for her to rest a bit more before eating out with Reena. He proceeded on searching Reena around the campus since she won't go too far and tends to stay in dark and quiet places when she's sulking about something.
Regis quickly found Reena as the little girl didn't even bother hiding her mana presence which Regis would never confuse for someone else.
Regis told Reena that they will be staying in a special room that he requested from Manaria. The eyes of the little girl brightly twinkled when she heard about it so she dragged Regis by hand and told him to quickly bring her to it.
When they arrived at the special training room, Reena wandered around the place excitedly.
'Whoah~ The shower room is so big! Reena can take a bath here with big brother~!'
'The small kitchen is a little bit small, but big brother can definitely cook something delicious for Reena!'
'Ohhh~~! My bedroom is better than I expected! It's even beside big brother! Only an annoying wall separates the two!'
'...'
So far, everything in the special training room made Reena squeal in happiness and she was even hopping around as she moved door-to-door. But Reena suddenly stops speaking after she entered the bedroom for Regis to use.
Reena went out of the room with slow footsteps and her eyes blankly staring into space as she moves towards Regis.
And that leads to the situation they are in right now—
"Is there something wrong with that? She's Arias, you know?"
"Of course little Reena knows that! B-But this place only belongs to Reena and her big brother just for the two of them! Aside from them, nobody else is allowed to sleep in this room, especially on big brother's bed!!"
'How can she use my beloved big brother's bed! Even I can only sleep with him sometimes! Don't tell me... They are already at that stage?'
Right now, Reena's face is beet red with some tears forming at the edge of her eyes and her body trembling slightly. She's most likely very embarrassed to scream what's on her mind, especially if the other person present is Regis. Or it is also because of her anger.
Regis on the receiving end can only stare at Reena dumbfounded. It's not that he doesn't understand what Reena meant by that. He was just overwhelmed a bit by Reena's words. After all, this is the first time he saw her like that.
'Big brother... He's finally replacing Reena with another girl...'
With Regis just staring at her silently for a few minutes, Reena also turned silent. Her body trembled stronger than earlier, her face now downcast and is being hidden under her silky silver hair. Although Reena can't see what expression she's making, still he can feel it. After all, with his sensitive senses, there's no way he can't hear Reena's faint sobs.
Looking at Reena, Regis face cannot help but soften. Without making a sound, he silently approached Reena very closely.
Falling in one of his knees in front of Reena, Regis pulled her small figure into his embrace and hugged her tightly.
Being tightly embraced by her big brother, Reena didn't hold it in any longer and finally cried unrestrainedly as she also tightly clutches at her brother.
"I'm sorry if I made you anxious. I know that I'm the only one you have in this world so don't worry, your big brother will never abandon you."
"Uuuuuuuuu— Uwuuuuuuuuuuu… *sniff* Of cosh*sniff* little Reena nows dat… *sob* Big bwother did evwithing he can *sob* and bot little Reena back *sniff* fom empines so des no way hel abandon Reena, but… *sob* but…Uwuuuu~"
With a hoarse voice, Reena tries to say something to her brother but she can't finish it as she began to cry again.
"Say no more, there's no way I'll forget about you just because I reunited with Arias. Don't be so jealous of her. Oh, and speaking of Arias. She was a bigger cry baby than you are from her childhood. Hahaha! Right… You two are definitely alike."
For a long time, this is the first time the siblings had a talk like this. With Regis always busy and their big age gap, they weren't able to bring out the feeling they have so Regis was a bit thankful for this sudden turn of events. As a result, even just a bit he was now able to tell Reena about how he actually feels.
"Hmmp!~ Don't lump little Reena to her. Reena is definitely better than that girl~ And when Reena grows up, she'll gonna marry her big brother!!"
Hearing that, Reena immediately stopped crying. Regis finally released her so he can clearly see Reena face.
Although she haughtily puffed her chest out and says all that, it doesn't sound convincing because it's coming from Reena who has a pair of swollen eyes, red from her nape to her ears, and her cute little nose that also turned red to the tip are blowing.
"Yes yes, you're better than Arias... Reena is best sister~! But you can't marry your big brother though."
Seeing that, Regis smiled in his heart as he fished his handkerchief in his breast pocket and wiped her runny nose.
"Pfuumm~! Umu… Reena wonders about that. She'll definitely make her big brother chasing after her in the future. Big brother will surely regret it later~! Oh, it's already getting late… Big brother, Reena will change her clothes for now~!"
Thankfully children have an ability to easily switch their mood 180 degrees. There's nothing visible gloominess or sadness in Reena's face and she's now beaming with happiness.
"Yeah yeah… Do your best to make me regret it! Wear some coat above your dress for it will be cold outside later. We'll eat dinner in the town later."
"Yes~!"
Seeing off Reena whose face blooming with her very cute smile, Regis finally breathed a sigh of relief and called out.
"You can come out now, Arias."
