Ur mom were single mom with 2 kids you and your 2-year-old lil sis Lea

One day your mom hired babysitter for Lea becouse she went on a business trip

You were out with your friends to go shopping at mall

When you came back from town you opened the door and closes it behind you then you remember that ur mom hired a babysitter for ur sister

When u enter the living room u saw the school's "bad boy" dancing to gwiyomi song

when he saw u he blushed "You didn't see anything!"
