This is just so fucking sweet and one of my favorite dj damn it. Kuroo is my ideal guy (the character he has here), he gets mad when Tsukki said that he is willing to let him go. It just shows how much he loves Tsukki and he gets hurt when he said those things. And ughhh he gave him a ring and it's obviously simbolizes his undying love for Tsukki.
Haikyu!! Dj - Kei-kun, Gomennasai Wa?
