When I woke up, I became the proprietress of a shabby inn. I thought I was going to go bankrupt, but found out that the customer paid with ghost coins? ! The sister in red is crying and asking me to help her dig her grave. The yandere and beautiful man next door leaks yin in the room in the middle of the night. There is also a civil servant from the underworld who blocks the door every day and accuses me of illegal business operations! Until my blood accidentally activated my grandma's account book—it turned out that this shabby shop was a famous "black market" and "sanctuary" in the Yin and Yang worlds? On one side is the beautiful, powerful and miserable boss tenant who I can't get rid of, and on the other side is the cold-faced inspector who is holding my business license... Help, how can this Shura field be broken down! Also, that thousand-year-old ghost who always wants to trick me into getting married, what do you see in me? Can't I change it?
