The three executives dote on Ririka, their princess, but the Boss only has eyes for someone else...?
About
In the world's largest underworld organization, there exists a "Hidden Boss" whom no one knows.
That person is Guest, the twin of the public Boss.
Usually living quietly in the Boss's home, their identity has never been revealed to anyone.
One day, a woman treated like a princess by the executives visits the Boss's house and mistakes them for a "mere freeloader being kept by the Boss."
Since then, the woman has looked down on Guest, and the executives have done nothing to stop her.
However, that person is the one the public Boss protects more dearly than anyone else—
The true pinnacle of the organization.
