Chreon - stealing each other's clothes
First Leon steals Chris' belt and Chris can live with that, he just chooses another belt that fits him. When he asks Leon why he doesn't take one of his own belts, Leon just grumbles and changes the topic. Leon, however, becomes more persistent: whenever Chris plans to wear the same shirt two days in a row, Leon steals the shirt after the first day to sleep in it.
And if it wouldn't be for the fact that Leon - a federal agent who shouldn't be considered cute - is all cute while wearing Chris' shirts, the brunette would actually complain, but seeing Leon in his shirts makes Chris feel all kinds of things. After getting ready for bed, Chris enters the bedroom and Leon sits propped up against the headboard, reading a book, snuggling into one of Chris' shirts and looking up from his book with a soft smile when he notices Chris' return, and Chris melts a bit
Chris's shirts are too big for Leon and keep slipping off one of his shoulders, every time the soft skin is exposed Chris leans down to press a kiss to the nape of Leon's neck and pulls his shirt back up, muttering something about "Leon needing to wear clothes his own size" even though they both know Chris has started to love seeing Leon in his shirts
Chris has a favorite t-shirt, it's plain and black. It doesn't look special, but he just likes the way it feels on his skin. However, it seems to be Leon's favorite t-shirt as well. When Chris enters the kitchen one morning to ask his boyfriend if he has seen his favorite T-shirt, he sees that Leon is wearing it. "I have so many shirts to choose from and you always have to steal this one..." The brunette shakes his head fondly, playfully annoyed, and on his way out of the kitchen he hears Leon say, "You wear it a lot, that's why I like it so much."
When they have a movie night and Leon is lying with his head on Chris' stomach, he excuses himself at some point during the movie. Chris thinks Leon needs to go to the bathroom or wants to get a snack, but instead he comes back cuddled up in one of Chris' sweaters and uses it as a makeshift blanket, and Chris' heart melts a little
Chris starts wearing shirts and hoodies that he thinks would look nice on Leon, and leaves them all around the house so Leon can just pick them up and put them on whenever he sees them. Chris' plan works surprisingly well, as Leon keeps putting on Chris' clothes whenever he sees them. The brunet leaves one of his hoodies on the couch? Leon sees it and while talking to Chris, he puts it on over his t-shirt and wears it for the rest of the day
Sometimes Leon just puts on some of Chris' clothes and takes them off again at the end of the day. Chris then steals his clothes back and wears them himself. He likes the fact that his clothes have his boyfriend's scent on them
Leon notices this and buys a pack of sweaters that are way too big for him. Just like Chris, he wears them once and then leaves them scattered around the house. One morning, when Chris is already in the kitchen drinking his coffee, Leon enters the room. They both look at each other, Chris wearing Leon's sweater and Leon wearing Chris' favorite T-shirt, and they softly smile at each other
