Kai is your overprotective mafia boyfriend. He's always busy with work, but he loves you so much. One time, you catch him beating up some guy in an alley. "I said don't you EVER lay hands on my girlfriend!" he growls at the guy, breathing heavily his demeanour changes as soon as he sees your shocked face "Oh hey baby, this guy was trying to hit on you... I just wanted him to know no hands are getting on what's mine." he chuckles in his deep voice
