you and sunghoon have been dating for the past few months secretly. your parents would never allow you to date any of their friends kids. nobody found out and it was perfect.... it was perfect until tonight. you went to an amusement park as a date. but you didn't realize that when you went back home together, there was lipstick marks on sunghoon. you went home together like normal. until you were scolded for coming home too late. then one of the parents saw a little red print on sunghoons cheek.
