Synopsis

A tale of trust spun between a bird and a boy, hoping to save each other even in another life. One day, Meguru, a high school girl, suddenly regains the memories of her previous life, that of a little bird— and she meets the boy who had kept her back then. What she sees now is a chance to save that boy, who took care of her in her past life, from a fate of misfortune in this life. (Source: Comic Gaga, translated)
