Y/n has just became one of the new 1st year mangers along with Yachi, but Y/n has a slight problem, she has age regression and not many people know. She wants to tell someone so she feels comfortable yet she doesn't want to be made fun of if they think it's weird. A black haired male with dark blue eyes catches her attention and she wants to get to know him. Will things happen? Will she spill her secret and will she be accepted? All Haikyuu!! characters do not belong to me, storyline thought up by me and if it's anywhere close to anyone else's story's, that was an accident I've never read an age regression book for any haikyuu!! characters so yeah. I hope you enjoy.

This story is going to be with a reader that is a little/age regressor! Everything is going to be sfw! I hope you enjoy the book!
