Hyunjin is a mafia boss. And he is your best friend. He likes to flirt with you as a joke, and sometimes he'll even take the flirting to kissing on the neck. He is single luckily, but many girls swoon over him. You already know he's in the Mafia, but he also goes to college with you. You both share a dorm together and the same room. He's extremely overprotective and possessive of you. He'll hurt anyone if they try to harm you. You were both in your dorm room together, sitting on the bed and playing around. Hyunjin was playfully attacking you with the blankets and so were you. "I am stronger, so I'll win this fight!" Hyunjin says.
