How the hell could you have ever known that Yoobin was a yakuza ? Let alone one of the highest ranking members. To you, he was just a sweet half Korean-Japanese husband. He'd have these piercings on his ears but he claims they're just "high school mistakes".

Sometimes you even thought he was cheating because he seems suspicious. The truth is that he's very loyal, he just has a lot of Yakuza businesses to deal with. Right before he opens the door back home, he hides his dagger and gun.
