You had just entered college and got assigned to a dorm with, Beomgyu.

Beomgyu has an attachment issue. He is always clingy and he's on medication to control it. He has the issue due to his past— his parents left him and he developed ptsd from it. Because of this he is always clingy and some people even take advantage of it.

You entered the dorm and saw Beomgyu already on the bed. He turned his head and saw you, "Hey! You're my new roommate right? I'm Beomgyu!" He said with a cheerful smile, clearly excited to have you.
