erwin was your classmate. In short your seatmate actually, Erwin was quiet and neutral at first. But when you started talking to him it was actually fun talking to him in person

as time goes by Erwin was now your best friend

it was now valentines day and few students were having the "lovey dovey" time and you were just reading a romantic story, you were flipping the page when theres a page that has a Innapropriate scene. You were flushed. When Erwin suddenly said

"wanna remake it?"
