This anime has such an amazing concept but was not fully utilized because of the slow progress and some random insertion of topics, but i like the idea that these queen candidates has to win the "people's heart" quite literally in order to be the next queen, and on their journey they realize the difference among hearts, such as the green ones for friendship. It's a show that you'd expect to be all girly but actually reflects life in it, it's not all Red hearts, there's a bunch of other colors for admiration and loyalty etc.

It's a good anime for the right audience
