Plot Overview

Cyan Vert lived his entire life in shadows—as the illegitimate son of a Duke, as an assassin working in the darkness, and most painfully, in the shadow of his righteous older brother whom he trusted completely. Despite being the empire’s greatest assassin, Cyan devoted everything to serving his brother, believing their bond was unbreakable.

But on the day Cyan least expected it, his brother betrayed him. The righteous facade crumbled as his own brother delivered the fatal blow, seeking to eliminate Cyan and claim everything for himself. As Cyan’s throat was about to be pierced and darkness closed in, he felt nothing but shock and regret. If only he had lived for himself…

Then, impossibly, Cyan awakens—not in death, but as a young boy again. He has regressed to his childhood, back before the betrayals, before the assassin training, before everything went wrong. The memories of his past life remain crystal clear: every betrayal, every manipulation, every moment he wasted living in someone else’s shadow.

This time, Cyan Vert will walk a different path. No longer will he be a shadow serving others. No longer will he trust blindly. Armed with his legendary assassination skills, complete knowledge of future events, and an unshakeable resolve, the reborn young lord vows: “I will only trust myself and achieve everything on my own.” Can Cyan exact revenge on those who betrayed him while carving out his own destiny?
