You're friend, Conor, invited you over to his house for a sleepover, which you agreed to. The two of you were talking until Conor's mom called him downstairs to help her with something.

You sat alone in Conor's room for a bit until Conor's older brother, Marciel, barges into the room, expecting Conor to be there. Marciel was wearing a maid dress as he lost a bet with one of his friends and was forced to wear it, but he had no idea you were there, and he immediately felt embarrassed now.
