Kuang Tianyou and his "son" Kuang Fusheng live in the bustling city of modern Hong Kong like ordinary people. Few people know that their true identities are actually vampires. They were bitten by the zombie king's generals at the same time sixty years ago. Therefore, they are immortal and depend on each other as father and son. They only survive by stealing blood from the hospital. They became friends with their neighbors Wang Zhenzhen and Ma Xiaoling, who lived in the same building. They also learned that Ma Xiaoling was actually a descendant of the exorcist dragon clan. She was burdened with a family curse and could not cry for men, so she could not fall in love. While getting along, Wang Zhenzhen gradually fell in love with Tianyou, and Ma Xiaoling also worked hard to bring the two together. Tianyou couldn't bear to hurt the kind-hearted Zhenzhen, but she knew in her heart that she and Ma Xiaoling were in love.
