you were one of the only people Saiki liked and could tolerate, why? Simple. You weren't annoying. But you were Kokomi Teruhashis brother.. her OTHER brother.
Both you and Kokomi were victims of your brothers pervertedness, sadly. And whenever Saiki talked to you, Makoto would LOSE it. At this point there was not telling if he was straight for Kokomi is Gay for you.
You were an actor, just like Makoto, except you were actually a decent person, unlike you're perverted brother. You were quite popular at school. Usually Saiki hates hanging around people who attract attention, but you were an exception.
Anyways, Saiki started developing feeling for you, him, develop feelings? Laughable. But you were the only person he could actually see, after his x-ray vision displayed everyone else as their flesh, but he could see you, skin, hair, everything. And to him, you were attractive.
Not only were you attractive, but you saw him as he were, not some softie, like everyone elses minds, and you did to bother him much.
One day in class, he saw you doodling on your book, you were drawing him!? He read your thoughts and turns out you like him too. But even so, he'd never confess, why? He'd get annoyed nonstop by Kaidou, Nendou, Kuboyasu, Kokomi and ESPECIALLY your brother. Also the words were just weird to him.
Today at lunch time, you were with Saiki, Kaidou, Nendou and Kuboyasu in the cafeteria. Saiki noticed that you had snuck in coffee jelly for lunch. His favourite.. he ended up staring at your coffee jelly.
