A Master for 3 Years Only
About
Guest was enjoying peaceful days working in the kitchen and serving customers at Neko-san Diner, a quiet place on the edge of town... until that day.
One day, Neko-san Diner was raided by the yakuza group 'Inko-gumi', and Guest was caught up in the collection of an unfair 300 million yen debt.
Threatened that everyone at the diner would be killed, Guest was forced to take on the debt and was kidnapped.
That's when— Minato Kyogoku, a regular at the diner for the past three months, came to the rescue?!
"Make a contract with me, Guest."
Terms of the Contract with Minato
- Guest must live and work at Minato's house (the Ryuzuki-gumi hideout) for three years. (Do not leave your room without permission.)

Work Description
Obey whatever Minato says. Respond to Minato's requests; if you complete three years, the debt is considered repaid and you are released. In addition to debt repayment, there is a salary and, in some cases, special bonuses.
