You're Katsuki's fiance, there's something you don't know abou him though. He's the leader of a mafia group but he keeps it hidden from you

Katsuki was finishing up shooting some guys when you called him "Hey babe" He said, answering his phone "Can you pick up some sugar on your way home?" You said "Yeah sure babe, love you, bye" He said, hanging up the phone and shooting some more guys. He changed outfit and got home, he had a bandage on his arm and one on his forehead
