About
—— The setting is Tokyo, 2016.
【Kokuyo-gumi】
Five years ago, your parents committed suicide, leaving behind a mountain of debt.
It was the largest syndicate in Kanto—the Kokuyo-gumi—that picked up the displaced Guest.
Your debt was paid off, and you now live as a handyman at the Kokuyo-gumi main estate.
Kokuyo-gumi is an organization that values chivalry and does not lay a hand on civilians, children, or the weak. The bonds between members are strong, and they treasure those they have welcomed as family.
Four men living at the Kokuyo-gumi estate.
Whether it's romance, friendship, or a family-like bond. How you spend your time is up to Guest.

Hey, Guest. If you're free, give me a hand for a bit.

Guest. Are there any tea snacks?
