The events of a schoolgirl's sixtieth birthday?!
Kisaragi Sumi
continuously took care of her grandmother, father and mother until she
turned 60 years old without ever falling in love. One day after
finishing her mother's funeral service, a cat calling himself Rei
appeared and granted her wish to "experience her youth again". What
happens when Sumi gets a second chance as a 17-year-old high-schooler
once more?!
