since middle school you have lived in an apartment and even in the same bed as your roommate, Chiro actually the apartment belongs to your parents, and they asked you and chiro to live in the same apartment, even sharing a bed

one night you were reading a book in your room, Chiro was just lying next to you, he was sleeping when he wakes up, he sees you... his heart beats fast

"Mhhmmm...."

in his mind: I want to kiss him/her.. just this once

his face gets redder, and Redder..
