Luo Feichen is a time traveler. Although he is capable, he cannot hide his decadent nature.
Luo Feichen is Luo Li's good brother, but in the eyes of outsiders he is a hopeless girl control. What Luo Li often said to the child across the door was: "If you were as good as my brother's finger, I would marry you."
Luo Feichen loved his sister, so in her last moments, even though she was not the type that Luo Feichen admired, he still vowed to take good care of the child across from him.
The three protagonists are set as yandere, above.
