I would say that this drama is like the embodiment of youth. It's so bright and heartwarming, really makes you want to go back to high school. It's fun, romantic and just chill, you mostly get to see the daily lives of four students. I think that their school days are what I always wanted and thought high school would be like (it's not), so it makes the audience really happy. Overall it's pretty light and there aren't any big obstacles, but I still think there are some important messages in this drama that will stay in your heart. This is probably the most heart-fluttering drama I've ever seen, just because it's so fresh and they're so young and naive. I also loved the cute qoutes they put at the end of every episode.

If you think this drama sounds interesting, definitely give it a try, I'm sure you'll like it a lot too! <3
