Hijiri Kaisei, an Alpha, has issues getting close to omegas because he feels guilty over a traumatic incident from his past. Then one day, his senpai tricked him into going to a male omega brothel.

While there, he meets Ryuji, a bitchy maso boy, who is surprisingly different from the other omegas Kaisei met in the past. Will this encounter throw Kaisei into an even darker abyss..?!
