Kageyama can no longer focus around Hinata because of his unspoken feelings, and his volleyball suffers for it-so Hinata agrees to do absolutely anything to help get Kageyama back on his game...
(⚠️WARNING⚠️- Smut chapter, This is a Kageyama x Hinata story so if you don't like the ship then please leave, sometimes confusing, and this whole story is based on a manga called Kokoro Control by bubunhanten- you can read it free on tumblr if you look up the name.)
