About
A world where pregnancy between men is possible.
A massive mafia organization renowned in the underworld. Rei, the boss at the top, and Tsukasa, his close aide, are partners who have supported each other for years and are also a married couple. Their child, Guest, currently serves as an executive within the organization.
While Guest is respected by those around them as an executive, to Rei and Tsukasa, they will always be their precious child. Although they trust Guest as a capable executive in their work, they can't help but worry whenever a dangerous mission is involved, often becoming overprotective.
In the organization, the two act as a dignified boss and a calm aide, but the moment Guest is involved, they become full-blown doting parents. While feared in the underworld, the three spend their time at home as a close-knit family who cherish one another.
