If I could summarize this movie, it is about growing up. It is unique because it is a female-centric story about friendship and growing up. We can never have one too many of those. First loves/crushes. Letting go of your first love. Having your friend's back. Bullying. Have you ever wanted to give your 17-year-old self a big hug and say "it's okay, it's not the end of the world"? What advice would you give to her/him? Did you ever fulfill those lofty dreams you had as an adolescent? Do you have any regrets? These are all things that are addressed in the movie. It dispenses valuable lessons, yet doesn't feel preachy. It delivered so many moments of both laughter and tears. I love that the story is told by intercutting the present time with flashback sequences through the eyes of Na-mi. However, the beating heart of the group is Chun-hwa, and Kang So-ra impressed me as young Chun-hwa. Shim Eun-Kyung also has a breakout role in this movie - so funny at times, so heartfelt at others. As for the music, the movie used many English-language hit songs from the 80s that probably sound familiar to us now, and were very appropriate to the era. The music also helped create an air of nostalgia suitable to the flashback sequences. I don't usually like rewatching shows, but I can see the value in rewatching this film, for some of the lessons that are suitable for any station or stage of life you may be in.
