-Bangchan is your roommate-

You've been accepted into a prestigious university at last. From the airport to the university, you rode in a taxi. One of the staff members welcomed you when you got there. They gave you a tour of the university. They eventually left you outside your dorm room after that. You had anticipated living alone and without a roommate. You went into the dorm and opened the door. You noticed someone using his laptop while seated on the couch.

"We share a room together. Avoid posing queries.”

This was your first impression of him, he said coldly, when he recently developed feelings for you and became obsessed, driving him insane just by touching you.

"She’s mine. avoid her at all costs!"

When your best friend taps you on the shoulder to get your attention while the teachers are holding you back away from Bangchan, he yells angrily at them.
