You Can't Have My Blood

Si-Yun’s life is defined by constant hardship. Burdened by overwhelming debt and a persistent medical condition that leaves him prone to fainting, he struggles just to get by. His fortunes take an unexpected turn when he wins the “Vampire Lottery,” a system that pairs human donors with vampires. As a result, he is matched with a vampire named Jin-U and officially becomes his designated blood provider. The two soon move in together under what is meant to be a strictly contractual arrangement. However, as they share their daily lives, the boundaries of their agreement begin to blur, and Si-Yun and Jin-U gradually find themselves falling in love. For the first time in a long while, Si-Yun feels that his circumstances are finally improving. Yet this newfound stability proves fragile. It is soon revealed that Si-Yun possesses an exceptionally rare blood type, a trait that quickly catches the attention of other vampires beyond Jin-U. What began as a simple contract for survival now places Si-Yun at the center of a dangerous predicament, threatening both his safety and the bond he has formed.
