[Heart-torture] + [Compulsion] + [Black Belly] + [Double Cleansing] + [Crazy/Yandere] + [Imaginary World View] The city of eternal night called "Saint Helier" is shrouded in industrial soot and fog all year round. The vampire clan "The Descendants of Cain" hides in the aristocracy and regards humans as domestic animals and playthings. As a human doctor, Ivy and the vampire prince Knox met on a rainy night, and the threads of their fate began to intertwine at that moment. Knox suffers from a rare "blood addiction". Ordinary human blood can drive him crazy, while Ivy's rare "golden blood" can make him calm, but in a sense, it also makes him fall into deeper desire and torture. It begins with the relationship between predator and prey, and ends with the mutual redemption of two gray souls.
