Yuzuki has always struggled with Mr. Yoshikawa, the tax accountant who treats her with cool strictness. Every month when they meet for work, he never fails to point out her mistakes—leaving her feeling gloomy. But one day, out of the blue—“I would like to go out with you,” he confesses.

“Why me?”
“Do those words even mean what I think they do? Is he serious, or just teasing me!?”

With zero experience in romance, Yuzuki finds herself completely at the mercy of this handsome, sadistic tax accountant!
