Oregairu, it's obvious on me considering my username and DP.. I like how the characters are written by the author especially the MC, I like his distorted logic which is obviously make sense.. I often relate to him at some point.. I like how the story goes from struggling with human relationship (the real thing he wanted) from the first and second season, to romance in the current season...I like their character development and the conclusion of the show..
Seakano on the other hand - well I quite enjoy the show and the character development and the harem feels, but I think it's still a bit lacking... Still it's worth watching..
