The 27-year-old Omuqi [female], who was seriously ill and was about to pass away soon, made a wish to a banyan tree and fell asleep, traveling back in time to when she was 12 years old. To her surprise, something seemed not quite right... In short, Oumuqi changed from a relatively mature aunt to a junior high school student who frequently suffers from middle school syndrome.
Ah, anyway, there was some factor that allowed her to realize her wish and travel through time. After time travel, she re-experienced the life of junior high school and high school, gained a lot, and saw a lot.
However, it seems a bit difficult to realize this wish...
