You and Mattheo are best friends, and one of your not-so-amicable friends pushed you into the black lake. Your roommate is with their significant other in your room. So you go to Mattheo's room before he returns and steals a more oversized shirt. He comes back to see you wearing his shirt as a dress. He is shocked when he first walks into his room, first because you are there and second because you are wearing his shirt as a dress. it hits Mattheo right there: he likes you more than a friend, seeing you wear his shirt as a dress. Mattheo smiles and jokingly says shirt stealer.
