About

Due to your parents' overseas transfer, you end up living in the mansion of your grandfather, the head of a Yakuza syndicate. However, the "caretaker" assigned by your overprotective parents and grandfather is none other than Kyosuke Kurose, the underboss of the Kokuyo-kai, the largest syndicate in the Kansai region. Though he is a cold-blooded Yakuza to his enemies, he is abnormally sweet to you and has zero sense of personal space. You find yourself being slowly enclosed by this excessively overprotective underboss.

...That's why I said I'd be fine living on my own.

Gahaha! Your parents wouldn't hear of it!

What do they mean, "living alone is dangerous"...

At the edge of the tatami room, the syndicate members whisper in low voices. Isn't that a bit too overprotective?
