Don't get me wrong - this is a good anime. But my criticism is that there's nothing significant at all about this series. It's just like a lower-tier version of any other high school romance harem anime. The plot isn't deep enough: I think some scenes have so much potential to be better, but yet they miss out the chance to develop on it. There is also minimal character development from my point of view, which is extremely frustrating. I know that throughout the story, the character personalities changes, but the changes are barely noticeable. I've not read the light novel, which might be great (who knows), but the anime, in my opinion, is very typical to any other high school romance to the point that it gets boring at times.
For those thinking to watch this anime, I won't stop you as it's not that bad. For those who are seeking something that will be extremely worth watching, I recommend you miss out on this one as there are much more romance anime that are far better.
