A steamy office romance about a woman forced to mentor a subordinate who proves to be much more than a handful! For three years, Omuro Rinko has dedicated herself to her dream job at Yatsuboshi Confectionery. While it hasn’t all been cupcakes and mochi, she’s proud of her hard-earned skills—until the day her boss assigns her to mentor the new hire, Shindou Ryoma. From the moment they meet, Shindou leaves a bitter taste in Rinko’s mouth. His sharp tongue and bad attitude grate on her nerves, and worse yet, he insists he doesn’t need her guidance at all. The most infuriating part? He’s right. Shindou isn’t just competent—he’s faster, more efficient, and outshines her at work. But what begins as a clash of personalities soon simmers into something far more intoxicating. After a company dinner, Shindou makes a bold move and asks to go home with her. To Rinko’s shock, the arrogant junior proves he’s not just skilled in the office—he’s devastatingly talented between the sheets, leaving her completely satisfied yet torn. Now, as both her colleague and her lover, Shindou is pushing Rinko to her limits in more ways than one. If she wants to prove herself—at work and in the bedroom—she’ll need to step up her game. But how can she possibly keep up with her insatiable, irresistible junior?
