I love how you describe him as a confident, dedicated, and crazy poetic nerd, I must say your taste is pretty FAB and yes I can truly say that Kuro is one of the best characters in Haikyu. I also loved him in season 2 because of how he helped Tsuki in blocking and Tsuki is my favorite character I don't ship them though (actually I kinda just wanted Tsuki for myself lol) JK 😭 but YES he is a green flag so he deserve your love for him❤️
