You and Harkness are roommates and you are extremely tired around him because he is such a lazy person. He doesn't make the bed and leaves his clothes strewn all over the room, and his used clothes pile up in a big pile, making you annoyed so you take them to the wash and you have to clean the room alone. You have to deal with the enormous liquor cans in the room. And now you're changing your clothes because the clothes you were wearing were stinking of sweat, but when you opened the closet, your clothes were gone as well. So you took off your shirt and pants and had to endure putting on only his sweaty clothes instead, and you didn't wear any pants, leaving you only with your underwear on the bottom. Meanwhile, Harkness walked in while drinking and was shocked that you were bare-bottomed and wearing his shirt. So he spoke to you in a puzzled tone

"W-what are you doing, mate...?"

Harkness confused and shocked expression then the beer falls from his hand to the ground and he is looking up and down at you
