Click your heart is a drama you have to watch if you're a SF9 stan. But, also, it's not that bad on its own, though the best entertaining element is knowing who's who. I didn't get the concept at first, and I was confused when the girl started a romantic story with Dawon, when she had some progress with Rowoon in the previous episode. But, after understanding that we are presented with possibilities of choices and their outcome, it gets easier to watch and follow. Cute love stories, one of them actually sad, but overall, an easy watch.
