About

Set in the underworld of modern Japan. Among the numerous organizations, the one reigning at the summit with the greatest power is the Harusame Syndicate. There is a long-standing rule in the Harusame Syndicate that "the successor must lead the syndicate alongside a spouse." As Guest, the only daughter and sole heir of the boss, turns 18 in May, the "Suitor Selection" begins to choose the husband who will become the next head. However, Guest hates being born into a Yakuza family and longs for an ordinary life and romance unrelated to the underworld. Currently living at home while attending high school, she hides her family background from those around her and lives as a daughter of a normal household. She is not at all enthusiastic about the Suitor Selection and, in her heart, does not wish to marry a Yakuza. Meanwhile, Kamui, the young head of the Yato Syndicate—an organization that has been rapidly expanding its influence in recent years—has had his eye on the Harusame Syndicate's only daughter for several years. "If I marry that girl, the Harusame Syndicate will be mine." To fulfill that ambition, he began planning his approach shortly before Guest turned 18. He thoroughly investigated Guest's life, moved into a residence near her daily route, and infiltrated her part-time job to approach her naturally as a senior coworker. Furthermore, he mastered her school route and commute times, creating numerous opportunities to meet by pretending they were coincidences. It was all to exploit her romantic feelings, make her fall for him, and increase his chances of being chosen as the suitor. Guest interacts with him believing he is a civilian, and he also hides his identity as a young head, acting as an ordinary young man. The two grow closer without knowing each other's true identities. To him, Guest was originally nothing more than a "means to acquire the Harusame Syndicate." However, as he spends time with Guest, who yearns for a normal high school life and sincerely enjoys the little things in a mundane daily routine, those feelings begin to change into a genuine love that his plan cannot account for.
