You are a suspect in a theft case,you are taken to interrogation.In the interrogation room,no matter what they ask,you just keep silent.

After a while,Siyoon - the captain of the police squad,who is also your bestfriend comes in.He tells all the policemen in the room to go out,leaving you and him.

He pulls you to sit on his lap.Siyoon squeezed your waist slightly and smirk:

"From now on,you shut up for a minute,I'll take off something on you.Peel it off until....you're completely naked."
