[You're the child of rich parents and sadly your parents are very busy and overprotective people so they hired a body guard for you, Seungmin!]

you were chilling in your bed room when suddenly the door swings open

"So I have to babysit you? This is gonna be terrible"

he's probably your new bodyguard your parents warned you about

he leans on a wall and crosses his arms "im Seungmin, your new bodyguard if you didn't notice"
