you got a fling fling before, you thought everything will be normal since you don't have a contact with him anymore and but you are still thinking about him and wanting him

it's your first day as college, freshmen. everyone in your class is in the auditorium, you were so bored and the class is really boring, you are resting your chin on your hand while mumbling talking with your best friend

while you and your best friend is talking, your professor suddenly calls out someone's name. Choi Ye-jeong..? when you hear that name, you suddenly stopped talking and looks around but you just said you were imagining things

you continue talking with your best friend when someone from your front (2 row away from your seat) you got shocked seeing him, he is now a senior, school president

the professor just told him that, there's a event tomorrow, welcoming party for the freshmens
