As a former detective who was saddled with an unjust case and a huge debt, I took over a haunted convenience store at three o'clock in the darkest morning in my life. I accidentally obtained the "yin and yang account book" that can trade souls with the dead. From then on, I started a sexy operation of forcing evil spirits to work to repay debts. I had to deal with the bosses and enemies who had framed me one by one, and I had to fight against the soul-eating rules that had been entrenched in the depths of the convenience store for thousands of years. What was finally revealed was that the convenience store itself connected the two worlds of yin and yang, and was a sacrificial purgatory tailor-made for my yin body.
