I call it a masterpiece. For me who likes anime and has read comics, it is the closest to the original work. It mainly tells the story of Hinata Shoyo being reborn as an adult and returning to the time when he was just born, but it makes up for some of the regrets of the original work. There will be some deviations from the original work, such as parallel lines, but basically the difference is not big. You will feel like you are watching the original work.
This is one of the better romance stories among volleyball boy fanfics. It doesn't describe too much about the characters in the original work. It mainly focuses on the inner activities of the heroine. This is a story about a girl who is confused and slowly finds the things she likes.
