Xia Ruochen, the editor-in-chief of "Niw Fashion" magazine owned by the world-renowned Niw Fashion Group, was told to break up by her boyfriend of seven years on Valentine's Day. After the breakup, she received a rose forced on her from a strange man. He lost consciousness before he could react.
After waking up, a pair of alien brothers Ling Muyu and Tongtong told her that she took her memory back to the day of her plane crash half a year ago. Her soul traveled to another girl named An Xiaoxia. Her mission was to prevent the accidental death of herself and An Xiaoxia on Chinese Valentine's Day.
In order to prevent herself and the girl from dying, she must use this identity to find the cause of An Xiaoxia's death. But she didn't expect that her and An Xiaoxia's death was not an accident at all, but there were more things that she couldn't imagine, why her boyfriend Zhou Ziyi broke up with her, what was her friend Tang Meiqi hiding from her, what kind of help would Tongtong, the child from the alien world who had been following her, give her, and what would be the ending for her and Gu Anyen, who had always been silently liking her and accompanying her.
Every step of the way was like a mystery, waiting for her to uncover it.
