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.

“I want to be a true demon.”

A boy not older than 20 years wished as he looked at the sky.

After suffering from the trauma for many years, he finally gave up on life.

People called him ugly, demon, and hideous.

He bared with it, but today he finally broke.

With a piercing pain in his chest, he died.

When opened his eyes, Logan found himself in another world and inside the body of a demon.

His wish was granted, but at what cost?

He had no power and was the lowest among the demons.

No one to help, no one to be with him.

But it did not affect Logan. Because he had something else with him.

‘Sin and Virtue System.’

Guiding him towards his goal to become a true Demon.

Logan’s conquest has begun, so be a part of it.

Otherwise, you will miss him.

The true Demon!

However, is the MC the 'only' one to have a system?

Hm?

Read the fucking novel and find out!
