Three years have passed since the trial that tore them apart. Choi Seunghyun, once feared, once adored, has walked out of prison a free man-his early release paid for by a mysterious hand. He believes it was fate. He believes it was love. What he doesn't know is that it was Ji Yong who pulled the strings. Ji Yong, the boy who once called him master, is no longer the same. Scarred, sharpened, and stronger, he has rebuilt himself piece by piece. But healing doesn't mean forgiving. Now, he has one purpose: to own the man who once owned him. Seunghyun expects devotion. Ji Yong demands submission. The game has flipped, the rules rewritten, and in this cruel dance of power and desire, only one can keep control. But when obsession and love are two sides of the same coin... who is truly the slave?

JiYong is one of the brightest human idols in a world where vampires rule the elite. He sings for them, donates blood to them... and secretly longs to understand their world. Seunghyun has tasted JiYong's blood without knowing it-calming, addictive, unforgettable. He never expected to meet him face-to-face... until a private concert brings JiYong's scent crashing into him like fate. Drawn together by instinct, curiosity, and a pull neither can explain, JiYong finds himself slipping closer to the vampire who can't stay away-while Seunghyun struggles to resist the human who feels dangerously perfect for him. In a society where humans and vampires shouldn't mix, desire is a risk... and JiYong may not realize just how deeply he's luring Seunghyun in.
