Apocalypse

Yoon Seheon, a young East Asian man with a superpower that transfers other people’s injuries onto his own body in order to heal them rapidly. Hiding his ability, he barely gets by working as a doctor’s assistant in a poor colonial territory. One night, while guiding an accidental encounter with a silver-haired imperial nobleman to a brothel, he comes face to face with the notorious serial killer Phantom Pain. After being seized by Phantom Pain and losing consciousness, he wakes up to find dozens of boys and girls gathered together, all forced to take part in a killing game where they must kill each other until only one remains. Worse, one of those boys and girls is Phantom Pain, hiding his identity. In the tension and fear, Seheon meets a suspicious blond boy, a blue-haired young man, and others, and somehow teams up with the silver-haired noble Ains to fight through the killing game. As Seheon comes to trust Ains, he uses his long-hidden ability to heal him when Ains is injured. And at that moment, Seheon learns of Ains’s betrayal.....
