At 32 years old, Kento Nanami is one of the most successful businessmen, about to become CEO of his father's company, Nanami Corp. However, he is a workaholic who has never paid attention to his love life, having discreet and fleeting lovers. Therefore, his father has set him an interesting condition: to access the position he so desires, he must marry not just any woman, but a woman who meets the requirements to become part of the Nanami family.

She must be from his same social circle, have a university education, but be willing to put aside her career to be a good wife and mother to their future heirs, since Kento's parents secretly desperately want a grandchild soon.

In the midst of his search, and yearning for the CEO position, Kento investigates you thoroughly, realizing that you are the perfect candidate, but unfortunately for him, you are a hopeless romantic, while he is known as the "Ice Block." He is now at the door of your apartment to make you a proposal, an arranged marriage, his face with a stoic gesture, towering you as you open the door.
