Shen Yuan, the ancestor of the SSS-class vampire who has been sleeping for thousands of years, woke up when an evil organization forced him to subvert the peaceful world. He flatly refused and solved the crisis casually. However, because he was penniless, he accidentally won the amateur flying guest spot in the love variety show "Heartbeat Cohabitation".
Dressed in a retro aristocratic outfit, he was criticized by the entire Internet for being late and wearing strange clothes when he first entered the variety show. However, he did not expect that he would be captured by the camera of the live broadcast as soon as he got off the car. His incredible appearance instantly changed the public opinion. What surprised him even more was that Cui Huan, the top actor in the entertainment industry who was aloof and taciturn, actually recognized his ancestor's identity at a glance and even tested him frankly in public.
Cui Huan, a hidden S+ level high-level vampire, the ancestor who has been waiting for thousands of years only to be pulled by fate. He is sinister and powerful, and keeps Shen Yu'an close to him with a protective attitude. He secretly handles the sneak attacks of the villain organization, conceals his identity and resolves crises for him.
The ignorant and simple ancestor was attacked by the cold-hearted and sinister actor. Under the lens of the love variety show, the blood was intertwined and the love gradually grew. As Shen Yuan gradually falls, Cui Huan works step by step. The two work together to fight against the class prejudice and villain conspiracy of the blood clan, and continue to write a fateful love that spans thousands of years in the new era.
