Kuroko no Basuke because it was one of my first intense special interest, I related to Kuroko a lot (And still do hashtag fictionkin, he was actually my first kin and it's almost the 2-year anniversary of me getting into KnB and discovering fictionkin) and would talk about it at least once every day for months
I liked the ending of the anime, it was really sweet, but I teared up at the end of the sequel movie because of my comfort character leaving, apparently the ending is different from the manga ending though so I'm sort of like what???
