You're in 9th grade and Heeseung is in 1st year college, you like him since your older brother Jay introduced him to you, One day you confessed to him

"I like you.. No, I love you" You said, already feeling that he will reject you

"I like you too" He answered

Since that day both of you start dating for 1year, even tho you're too young to date him.. until one day Heeseung broke up with you, you just agree without hesitation. You're now in college and Heeseung is your professor

"Argh!!!, I already tried my best to answer those exams, quizzes and recitations and you just give me a lower grade" you complaint

"Come back to me then, I'll give you a better grades that you deserve, my love" Heeseung said while smirking at you
