Summary
Oikawa Tooru always thought his greatest victories would happen on the court.
Turns out, they’re at home.Years after the rush of championships and packed stadiums, Oikawa is learning what it means to build a life instead of just a legacy. With Iwaizumi at his side, Hanamaki’s steady warmth, and Matsukawa’s quiet devotion, he’s no longer just a setter or a captain—he’s a mate, a father, and part of a pack that somehow fits together perfectly, flaws and all.
Through late-night talks, old scars, Alpha instincts, Beta dramatics, and the chaos of raising kids who inherited all of their parents’ attitudes, they build something softer and stronger than any trophy: a home.
This is the story of how they got here, how they stay, and how Oikawa learns that “happily ever after” isn’t an ending at all—it’s a journey.

Summary
This is an omegaverse yakuza story, which means quite a bit of dark material is referenced. If you are uncomfortable with that then this story is not for you, please don’t force yourself to read it.
They say the dead don’t speak, but Kuroo’s presence lingers in every shadow, every memory, every piece of Kenma that refuses to let go.
Seven years ago, Kenma was happy, living a normal life in rural Japan with his best friend and alpha, Kuroo. But an attack takes everything from him, leaving him alone and scared. Taken in by a yakuza syndicate, Kenma has to learn to live again.
Or
A story of overcoming grief and survivors' guilt, angst with a happy ending.

Summary
Iwaizumi Hajime likes to watch his omega get railed by other alphas. He knows that it doesn't make sense, but he can't help it. He loves when Oikawa's hole is stretched out, slick, and hot from being fucked by someone else. That's just how it is. And Oikawa loves making his alpha happy, not that he can complain about all the great sex.
Matsukawa is just the newest in a long list of alphas that get to taste Oikawa's hole. And really, he has no complaints because he is rather turned on being watched by Iwaizumi, too.
