Kageyama and Hinata are happily married and we may or may not still get some action from these two but this story is based on their oldest child. Haruo. Kageyama Haruo unannounced in the second gender is now a 3rd year in Karasuno High, the high school both of his parents went to. His little brother Helios, just entered Karasuno as well as a 1st year. Another year but the last year for high school volleyball. But to Haruo's horror, Tsukishima Rui was in the same class as him. When he found out his second gender, oh boy he was in for a treat. Probably smut so proceed with care! I do not own anything except the Ocs that I made which are the second generation. I do not own haikyuu itself or the art for the cover. If the artist would like me to take down the cover art please do say so and I'll take it down immediately. Thank you!
