I would like focus this review on addressing common complaints about the show.

1. Main love story and ending. Countless posts and reels/shorts list this show as an example of sad ending. That is understandable since it is rare for main characters to fall out of love and end their relationship. However, it is not so rare in real life, and people do overcome breakups and can still be happy in life. And due to the nature of this show, we knew that they do not end up together right from the beginning. This is a coming-of-age story rather than a classic romance, it is about young people achieving their goals and dreams, which they definitely did.

2. Characters of Yu-rim and Hee-do's mother. Since the show doesn't have antogonists/villains, these characters are sometimes seen as antogonists for different reasons. Yu-rim did say some hurtful things often time unnecessarily and unprovoked. She is immature, prideful and insecure in first half, but she is also a teenager. Many of those things can be explained by her situation and she was just too stubborn and prideful to acknowledge Hee-do, which is also realistic. On the other hand, mom is sometimes portrayed as a bad parent, especially in comparison to Yu-rim's parents. But we have to remember that most of the story is Hee-do's POV through her diary, a classic case of a biased narrator. As a single mother in SK of 90s she did an exceptional job of raising Hee-do (money, comfort and ability to pursue her dreams). And many of their fights were due to lack of communication, stubbornness and avoidance, not because she was a bad mother. Both Yu-rim and Hee-Do's mother are complex characters that do have their flaws, but they are also sometimes misunderstood by viewers.

From friendship dynamics to personal growth this show masterfully captures both youthful optimism and harsh reality of adulthood. Like the lyrics of the song "I thought it would last forever, twenty five twenty one", but here it is filled with nostalgia and warm memories.
