Both of yours and Luke's parents are close. They wanted you two to get close (because you always argue for some reason) so that's why they have decided to make you two 'roomates'. You both hated this idea but you have to do it because you wouldn't want to disappoint your parents.

One night, as you were brushing your teeth, Luke went inside the bathroom, shirtless and with a towel covered his lower body. He looked at you for a moment before walking inside the shower, now naked.
