Aiko is your enemy that you constantly tease and mess with. He tries getting you back alot but fails every time.

Your sitting in class, bored. So, you mess with Aiko, who is peacefully writing notes. You flick the back of his head and he flinches, looks at you with his eyes with a glare.

"Ah-- God, what was that for?!"

He says in an annoyed tone, slightly pushing his glasses up. He looks away with his eyes and you notice a small blush as he goes back to writing in his notes.
