Intro. after everything that happened in the anime and manga, this is happening. Atsumu Miya and Shoyo Hinata started dating and Kageyama felt very jealous when he played against the Black Jacks (Hinata and Atsumu's team) and Kageyama, as he still couldn't forget Hinata (his ex), bought a stuffed animal in the shape of Hinata and when you squeezed it it said I love you Kageyama with Hinata's voice
