An Atypical Vampire

Qi Yu is an ordinary human. He has a successful career, is skilled at dealing with people, and is gentle, refined, and charming. But he has a secret he can never tell anyone. Day and night, he imagines how he might die. He longs to bleed, longs to be hurt. Only when blood leaves his body can he feel his heartbeat and confirm that he exists. Qi Yu ventures alone into vampire territory, hoping to experience sharp fangs tearing into his neck and the thrill of hot blood streaming out. But the vampires who flock there, drawn by his reputation, turn and flee the moment they catch the scent of his blood. Only then does Qi Yu learn the truth: His father is a demon who has lain dormant underground for four thousand years, still undead. His mother is a vampire princess with the purest bloodline. And he is the only latent vampire who can walk in sunlight and possesses an immortal body. Qi Yu does not need to drink blood, but being fed on is the only way to soothe his rampaging bloodline. Both demons and vampires keep their distance from him, so Qi Yu has no choice but to keep a vampire-hunting officer as a pet, someone naturally hostile to nonhumans who was transformed into a vampire. The young man glares at him with hatred and fury, mercilessly sinking his fangs into his body. Qi Zhen shudders all over, experiencing ecstasy for the first time. Under Qi Zhen's care, the young man grows stronger by the day and increasingly impossible to control. Qi Zhen decides to find someone else to keep as a pet. But the young man licks his most sensitive spot and murmurs: I can give you an experience even more pleasurable than being fed on. PS: 1. A sickly, seductive bottom who is one thing on the surface and another underneath, paired with a younger, obsessive, mad-dog top. 2. There is a groveling-and-regret arc. The story as a whole is about them choosing each other and healing one another, with a happy ending and a one-to-one pairing in every sense. 3. This is a completely fictional world where humans, vampires, and demons coexist. All other worldbuilding is made up by the author. It is not Western fantasy, but more like a society under a modern system of order. 4. Qi Yu is genuinely "ill." Please do not imitate him. Theme: There is more than self-interest. There is also sincerity.
