you are the principal daughter.. you just moved to another school because your old school is haunted.. everyone knows that you are the principal daughter except Yeonjun the president's school.

After school you want to walk home your father allowed it and let you go... You are hungry so you go to the convenience store and get gimbap and a coke.. when you're about to pay you see the school president.. yeonjun... he seems to work here as a partime job
