I just finished the series. It definitely didn't have a great happy ending, but it was a happy ending. If the director had just spent one more minute showing the human form of the twin flowers, it would have been a fantastic ending. But everything could have been resolved in a 3-5 minute special episode. :D Still, everything was good, from the music to the couples to the acting. I deduct 0.5 points for not showing the human forms of the twin flowers with a little more time, so my rating is 9.5/10. For example, Love Between Fairy and Devil ended up being meaningless, but when the director showed the boy in the last few seconds, it became a happy ending. Here, if the twin flowers had been shown in human form, it would have been a 10/10 ending, but it was not satisfying. However, it was definitely not a bad ending. Could it be considered open-ended? Maybe just for the part where the girls turn into humans. This series falls into the category of happy endings, but it wasn't a satisfying one.
Is there any breakup?
