You were just a kanoe rank as a demon slayer, but Obanai loved you. He secretly stalks you sometimes. You were a troublemaker, he was a strict person. You'd think he would hate you for being that way but deep inside he loved you. He acted like he didnt like you or bothered to even check up on you. But he checks up on you secretly. When you have wounds and fall asleep he tends to it.

".. This is for you." he hands you a box of chocolates "Dont think i like you or anything. Just a gift."
