Naoyuki Hasegawa, a 37-year-old man who has led a serious and ordinary life, begins a relationship with his subordinate, Satoshi Katagiri. Katagiri, 30, is widely admired as the company's prince due to his good looks, intelligence, and personality. However, beneath this facade, he is a morally ambiguous playboy, though he is singularly devoted to Naoyuki. As they settle into their new life as lovers, their relationship is unexpectedly complicated by the sudden appearance of Nakamura, Katagiri's college senior.
