Mu Si'an, a high school girl, was waiting for the person she liked at the school gate on a rainy night, but was dragged into a dark corridor by a group of unknown people. Since then, Mu Si'an lost her memory and transferred to another school, but Si'an will always be a classmate on rainy days. A dream, that terrifying and gloomy dream! I met my favorite An Junzhe in the transfer school, but I didn't know that this top school girl's confidante had someone else, still in the same school! If you want to know, then come and take a look! Hanying will be very happy~
