Damian, a Centurion of the Punishment Unit of the Baroque Kingdom. “Damn it.” Just once. If I were given just one more chance… ‘I would have truly conquered the battlefield with these guys.’ At the age of 30, he closed his eyes on a nameless battlefield. But when he opened them, he found himself back 17 years in the past. And this time, he had a perfectly functioning mana core that could wield magic. ‘This time.’ I will rise higher than anyone else. I won’t be swept away by the turbulent times. ‘I will conquer.’ Damian, who has returned to the past, wields his spear toward the world.

I died in an explosion—a betrayal engineered by the man I trusted most.But instead of the end, I woke up in a new body. A noblewoman’s body. Evelina, disgraced and hated, accused of poisoning the Crown Prince of a kingdom where werewolves rule the land.And worse?The man whose life I supposedly tried to end is now my fated mate.Damian, the Crown Prince, is as cold as the moonlight that binds us, his piercing silver eyes filled with distrust every time they land on me. He doesn’t believe my innocence, and frankly, I don’t care.My only priority is survival in this dangerous, medieval world—and figuring out why fate decided to shove me into the life of a traitor.But the longer I’m near Damian, the harder it is to ignore the pull between us—the undeniable heat of the mate bond that makes his touch electric and his presence intoxicating.Enemies lurk in the shadows, including the woman who thinks she should be his Luna. Court intrigue spirals out of control, and the person behind Evelina’s betrayal might be closer than I realize.Damian’s trust is my only shield, but when the truth of my transmigration comes to light, I’m not sure even that will be enough to save me.Because in this world, it’s not love that conquers all—it’s power. And mine might not be enough.
