This anime is pretty good imo, a little comedy, romantic, chill. The animation is fine, the art style is really impressive, specially the emotional of Akira, cute and beautiful. The background is good enough. Some people complain about the frame-rate of this Anime but I think it's okay.
I specially like the OST of this Anime.
The studio which product this anime, is the one producted Anime "Wotaku ni koi wa Muzukashii" also.
There's also a Live-Action of this Anime.
