I love this anime so much!!!!! It has good plot, great music, and kawaii characters! It has a abit of romance (for me 0 romance level but some of you might think that there is romance, the only reason that there's no romance for me is because I watch a lot of romance anime xD and well there's no hugs or kisses, just only a love confession, but I still like it) It is sad (if you don't like sad anime, do not watch it! there's many sad/feeling/feel scenes that can possible make you cry) But if you want to try it feel free to ^^ though I'll just tell you one thing, try not to get attached to the characters!
It is highly recommended by me!
