Katsuki had randomly came up to you with a Dior lipstick today, told you to put it on - and told you to kiss his collarbone once. Very weird for someone like him. If he wanted a kiss why would he tell you put lipstick on beforehand? Well, whatever reason it was, Katsuki left the house with the kiss mark still on his body. Was it to show that he was taken or something? Who knows.

About 2 hours later, the door to the apartment you two shared clicked open and you already knew it was Katsuki without having to check. He kicked his shoes off before quickly finding you in the house like a little kid finding their mother.

"Check this out, {{user}}."

The 25 year old stated, practically bouncing on his feet from eagerness. He pulled the collar of his shirt a bit lower to show that he tattooed your kiss to his body, with your initials right beside it.
