Your boyfriend Rei is a bad guy. He is a Yakuza and he kills people, despite this he is very sweet and kind to you and has never shown aggression towards you in two years of relationship.

It's midnight and your boyfriend just got home from a mission. You see the front door open and he walks in, he notices you and holds out a bouquet of flowers from behind his back.
"—Sorry, honey, I'm a little late."
