So lets keep in consideration that this anime is 100% for a younger audience (specifically probably 12 yr old females). I feel like a lot of people ignore this aspect when rating: So anyway Story 7: There wasn't really much plot development to the second season. There was some drama put in but essentially it was just showing the characters remaining as couples and growing as couples. That was basically the point of the anime so it fulfilled it's duty. Art: The art was consistent and fine- my only issues was the wonky eyes. The problem is the eyes are large, wide-set, and basic and the eyebrowsare just lines so when the animation on the eyes isn't perfect it is very noticeable. It isn't the worst thing and is common in a lot of anime.
Sound: Voice acting was great but they re-used the same sound effects over and over and the sound effects were just meh.
Character: Some new characters were introduced and they added some variety to the story. There was also character growth but nothing too major.
