Girl Kiera was born in a happy family formed by humans and vampires. Her grandfather, Zongjiro (handle Benming), wanted to coexist with human beings, so he invented drugs that could age and vowed never to suck human blood. So he lived in the bright sun like a human. However, a disaster suddenly struck, and the mysterious vampire killed Kiera's parents to punish them for their cross-racial union. After that, Kiera followed her grandfather to Yokohama and settled down at the 120-year-old vampire bakery. For example, after a few years, Kiera (Tonggu Meiling) has grown into a beautiful and fashionable lovely girl. She met Mei Qi (Meng Gengru), a girl who tried to commit suicide, and met her good friend Ah Zhe (Xiangtai Tatsuka) once again in her childhood. The vampire's different kind of youthful life unfolds leisurely, but can she find a way that is very different from her parents?
