Liang Xia had accomplished nothing at the age of 20 and was living a very unsatisfactory life. One day she picked up a book on the road. The book asked her if it could allow someone to go back in time and save her, who would she choose? Shen Ci chose herself without hesitation.
5-Year-old Liang Xia has a little fairy who has an adventure. She can hear a strange big sister talking in her heart. The big sister knows all her little secrets and will accompany her to do homework, watch TV and tell her stories.
13-Year-old Liang Xia has a super power. Every night when she dreams, she dreams of a ghost. This ghost is weird because it appears every day. She can't help but tell her what happens every day. Inexplicably, it seems to be giving her courage and support.
18-Year-old Liang Xia is bound to a system, but this system is quite stupid. Not only is it not as omnipotent as other systems, it can't even solve the simplest math problems. But the system doesn't dislike her for being fat or ugly, and they agree to be best friends with each other.
