Its a great anime after you watch one that is either way to serious or feelsy.
It isn't that great in terms of a sophiscated story but is is kinda heartwarming and happy sort of anime.
watched it after Your lie in April so it definitely cheered me up.
art is pretty good but i have a bias towards clean/smoother animations
characters are underdeveloped but its all happy endings so all good after you finished a trip on the feels train.
reminds me of a dating sim now that i think about it...
also there's a bit of fanservice but nothing a 'mature' person can't handle
