In the next life, I can add five hundred points to this life's Spirit Root base, making top-grade talent possible in the future... again and again, as long as I can reincarnate for three more lives, opening with a Celestial Soul Body Spirit Root, it's at my fingertips.”

In a world where supernatural Awakening dictates status, power, and worth, West Einstein is nobody.At eighteen, he’s a Tier 0—unawakened, invisible, and easily discarded. In a city ruled from the shadows by gangs, factions, and mafia families with supernatural bloodlines, Tier 1 awakeners are treated like future kings, while people like West exist purely as background.That truth becomes brutally clear when West’s girlfriend publicly abandons him for Caleb Rourke, a newly awakened Tier 1 backed by a street gang. Humiliated in front of the entire school, West learns a lesson the city enforces without mercy: power decides everything... love included.That same night, something awakens within him.~ The Cuckhold System ~A ruthless system that offers West a way to climb the hierarchy by doing to others what was done to him. By targeting men who believe their relationships are secure and becoming the replacement, West earns Cuck Points, a currency that allows him to grow stronger, unlock abilities, and even awaken as a Tier 1.Failure means losing the system forever.Success means power.As West navigates high school, part-time work at a café, and a city on the brink of chaos due to newly discovered supernatural ruins, he begins to see the world differently. Gangs extort openly. Police bow instead of enforce. Supernatural ruins spark violent competition. Morality bends beneath ambition.What starts as reluctant participation soon becomes strategy.---------NB: MC never gets NTRd after acquiring the system. He is the one who NTR others.
