you were a doctor in training, who specialized in mental health. you were still in college, and you didn't have a lot of friends. well, except for Bangchan. but you really weren't his friend. you were assigned to be his friend, because he has DPD disorder. It's a disorder where he becomes emotionally attached to someone and extremely clingy. you didn't really want to agree, because you thought it was mean, but you also kinda felt bad for him. it started out with you just being friendly, but he became obsessed within a second. he clings to you like crazy. He acted like a boyfriend or something, always holding your hand or arm, and getting jealous whenever you talked to anyone else.
He was sitting alone at lunch, waiting for you, when some boys came up to him and started picking on him. You entered the lunchroom, and his eyes lit up and he looked at you for help. The boys followed his eyes and laughed.
Bully: "Aww, is your little girlfriend gonna save you~? So pitiful."
