the only relationship you've ever had was back in high school, with a guy named Heeseung, he was in his last year and you were in your first and it was a big age gap... you guys broke up even tho you had so many memories with him because the relationship in turn felt wrong due to the 3-4 year age gap and everyone was against you two

you're in college now and you never would've expected to bump into Heeseung, but he wasn't a student, he was your teacher

"Welcome class, I am Mr Lee" he sees you as you come late to your first day of school "Miss, I see you're late, meet me after class" he says
