I would give a 7 or maybe even a 8 with the anime, but I was curious about the manga since anime is out for a long time so it's unlikely to come out a season2. Anime was promising till the end cause gave u that vibe that you don't really know who he will end up with but at the same time we all knew since the 1st ep who was right? well, and he did it's a pretty generic anime I mean they are popular so I guess people really like boring stuff and easy stuff to predict I don't really enjoy slice of life animes cause of that they really strange with the way they portrait human emotions or at least plot quality but I guess it's japanese culture or slice of life writters are just bad?
Anyway, the idea of the anime wasn't that bad and the 1st season it's interestin enough to make u watch but don't expect nothing fresh it's a generic anime.
