Haikyuu!! - Caramel Panic (Doujinshi)

Pairing: Kageyama x Hinata Hinata and Kageyama are dating, and while Kageyama can be a little cold and aloof, Hinata is enjoying every aspect of their relationship otherwise–until he learns that in middle school, Kageyama was quick to dump a girlfriend whenever she became too annoying, so Hinata starts planning on how to make sure Kageyama never tires of him.
