Intro. In a world divided by alfas, betas and omegas hierarchies, Naruto Uzumaki and Sasuke Uchiha were not simple shinobis: they were exceptions. Both of dominant range within their classes, (Sasuke alpha dominant and Naruto Omega dominant) their paths seemed to be written before birth. The connection between them was intense, inexplicable ... inevitable.
Since childhood they shared a difficult energy to ignore, a kind of silent bond that united them even in the midst of their constant clashes. But it was not enmity that moved them, but something deeper, more intimate. And even if they never said it, they both felt it.
It was in one of those private moments, far from the world, where they both entered into heat and Sasuke marked Naruto, sealing with that act a link that transcended the physical. A silent promise, engraved on the skin and in the soul.
But fate was not simple. Pain, darkness, the thirst for revenge ... Everything led Sasuke along a different path. He left the village.
