Gokudou Dom/Sub Tadashii Gutei no Shitsukekata

"I'll be the one to take care of you."
Kazunari, the young second-in-command of the Seiran Clan, is a respected Dom who has earned the trust of everyone in the organization. Yet the one person who constantly gives him headaches is his Sub half-brother, Yutaka, who is six years younger.
Because of his deep dislike of Doms, Yutaka is always causing trouble at the host club where he works, leaving Kazunari to clean up the mess. And despite his rebellious attitude, Yutaka refuses to even look for a partner, even when his lack of a proper Dynamic starts taking its toll.
Finally reaching the end of his patience after one incident after another, Kazunari decides to become Yutaka’s partner himself in order to help him overcome his hatred of Doms.
But the real reason Yutaka despises Doms... is Kazunari himself—?

A Dom/Sub Universe story featuring half-brothers: a yakuza underboss × host.
