Anime was pretty much exactly like the manga and it doesn't really add much, up to you whether that's a good or bad thing. Very easy to rewatch when I'm craving some cute bl since it's so short at like a minute per episode. Simple and cute, so it's hard to criticize other than the lack of animation. Speaking on the lack of animation, I do definitely wish there was more motion, but it's still enjoyable. Overall not bad, but it's better to just read the manga for the first time.
Oh and, this should be a given, but don't watch it if you don't like boy's love.
