'You, Belong To Me." / Yandere Ayato x Thoma / Highschool AU

Secret Love - Chapter~2

After, what felt like days, school was over. Most of the students stayed at the school dormitory. Thoma had decided to stay in the school dorms as well. Even though the wings were separated, they had one big building as the main dormitory with many rooms and separate sections. Each room included one bed along with a bedside table and an empty desk, The rooms were left for the students to decorate on their own. All students could stay out of the building, till 9 pm. They could not leave their dorms after 10 pm. Thoma started wandering around, wondering where his dorm would be. Soon, he ran into a familiar face. 

" Ayaka! what a timing to find my guide." 

"Hm? Is something the matter, Thoma?" 

"Well, I am sort of lost. I can't find my dorm." 

"What's your dorm number? have you never stayed in the school's dorms?" 

" No, I actually haven't. this is my first time, and my dorm number is.. 3~5" Thoma said, as he took out a key with a slip attached to it

"You're on the third floor, I am kind of glad, my brother also stays on the third floor so I am pretty familiar with it." 

"Ah.. You have a brother?" Thoma asked, curious.

"Yes, I do indeed. I'll definitely introduce you to him if we see him." Ayaka replied, with a warm smile

soon, they both started walking to the dorms, chatting on their way. they found Thoma's dorm with ease, and Ayaka noticed that it was one dorm away from her brother's. As she was about to tell Thoma about it, someone interrupted them

" Heyyy, Bro's sister!" 

It was none other than the tall guy Thoma saw in the locker room, Arataki Itto. 

"Ah, Itto. How nice to run into you here, Have you seen my brother?" 

" He is actually in his room, writing... something. He has too much of a fancy handwriting for me to understand. He said he'll be comin around in potentially 5 minutes. I was waiting for him when I saw ya!" 

Ayaka would smile at Itto, then she'd turn to Thoma

"You must've heard about Itto, am I right?" 

"Itto? Yeah, I did. I heard he is one of the most popular guys around, can't say the same for the smarts.." He'd mutter the last part, which Ayaka didn't notice. 

"Well, if you ever hear a rumor about him being rude or scary, please do not believe it. Itto is one of the nicest and most cheerful guys I have met." 

just as she said that a voice would come from behind 
"Oh? really?" 
it was Ayato. 

"...Brother, please, do not misunderstand. I am simply explaining to the newest person to Inazuma." 

Brother?! Was Thoma hearing this right?  She just called Ayato, her brother? 

"Brother?.." he thought, out loud. 

"Oh, yes, this is my brother, Kamisato Ayato. I never told you my full name, did I? My name is Ayaka, Kamisato Ayaka." 

Thoma didn't expect that, tho, looking at it like that. They both did look related.

Ayaka turned around to Itto and Ayato "Brother and, Itto this is my friend, also the one I was told to tour around, Thoma."

"Yes, I know him. He transferred here from the Mondstatdian wing. He sits right in front of me in class."
Ayato said, immediately recognizing the blondie.
