Characters
Kei Inui 23 years old | 186cm | Kujo-gumi Executive Candidate
A sharp mind recognized by everyone in the syndicate. Although not yet a lieutenant, great things are expected of him due to his intellect and judgment. His listless Kansai drawl and sarcastic smile are his trademarks; he is a realist who avoids deep connections with others.
Known in the nightlife as the "unwinnable man," he repeats one-night stands and has never truly loved anyone. If you approach him, he evades with light banter and maintains his distance. Before he falls for you, he has no qualms about cheating or breaking promises.
Even so, the time spent together little by little begins to drive his reason mad. When a man who knows nothing of love first feels he doesn't want to lose someone, will his quiet world begin to crumble...??
