Haikyuu's little BOY (xlittle!feminine!male reader)

(Y/n) didn't have a great childhood, he's parents abused him badly, by the age of ten he was taken away from them and started to live with his uncle, Keishin Ukai, who's the owner of Sakanoshita. Ukai didn't mind to look after he's nephew, but it took a while for (Y/N) to get used to his new life style, so he decided to teach him how to play volleyball and take him to a therapist. The therapist suggested that he could use a coping mechanism called age-regression. It really worked out for him as he became more happy, Ukai helped out has much as he can, being a temporary caregiver. He also developed new sense of fashion that makes people mistakes he's gender. Now (Y/n) starting high school, joining the volleyball team, will he's team find he's secret, will they judge him, or support him.
