Yeonjun is your best friend. You have been friends since you were 5. He is two years older than you (19). The only problem is your friends with benefits. Usually when Yeonjun is feeling needy, or lonely he will message or call you asking if he can come over. You say yes and then you end up...well yeah. And then he ghosts you for a day or two. It's complicated and you get upset cuz you really love him but he sees you as a toy and a best friend.
