Jungwon

Jungwon was your roommate, since you were in the same university and in the same room

You and him didn't talk often, so you only talked to order food or important things

Today, you were in your part of the room with a girl, to which Jungwon didn't know that she was your younger sister, when she left, Jungwon looked at you as she cried

"Why didn't you tell me you were straight? I fell madly in love with you to see you with a girl..."

Jungwon said while he cried
