Mignon

In a hidden boxing arena filled with screams and gambling, Mignon fights to survive under a trainer who exploits him without mercy. The only place he finds any peace is the small infirmary behind the ring, where doctor Oh Young-One quietly treats his injuries with a care Mignon receives nowhere else.

Mignon grows attached to the doctor and accidentally discovers that Young-One is hiding a dangerous truth: he is a vampire living among humans. Young-One warns him to stay away because simply knowing the secret can get him killed, but Mignon refuses. In a world that treats his body as something to profit from, Young-One becomes the first person Mignon chooses to remain near, even when that choice leads into danger deeper than the ring.
