Awakening as an Esper, Haewon falls from a precious young master to a test subject at the Center. Stripped of human dignity and subjected to experiments, he spends years with only his brain extracted. Unable to endure it any longer, Haewon gathers all Espers and Guides to the Center, manipulates their minds, and drives the Espers into a frenzy, resulting in everyone’s death. And then, Haewon regresses—after sensing someone entering the control room just before his death.

But wait, isn’t this a bit too much?

Even after regressing, I’m still that horrific Esper? And… a eunuch, no less?

Traumatized by the events of his past life, Haewon refuses Guiding and lives dependent on Guiding drugs.

One day, through his brother’s introduction, he meets Chae Jinheon, a Guide with a high compatibility rate. Haunted by horrific memories of male Guides, Haewon vehemently rejects the idea, but unable to ignore his brother’s concern, he reluctantly signs a “Pair Contract” for money and comes face-to-face with Chae Jinheon.

But… this guy…

He’s way crazier than I expected.
