This movie could have been another classic romance between high schoolers but was much more than that thanks to the nostalgia throwback (as it is set in 1999) and its bright and pure atmosphere. In addition to be about romance, I appreciate a lot the friendship thematic underlying the whole plot.

The story (especially) in its first half did not surprise me at all, as I guessed from the start the "twist" but it did not bother me as the build up to get there was very sincere and satisfying. The second part of the film levelled up in a simple and beautiful way the stake of the love story. It was painful and healing at the same time and left a lasting impression on me as a viewer.

The cast was good, I was not very familiar with any of the actors and actresses playing the 4 main protagonists but they did very well. Kim Yoo Jung playing the heroine was particularly great in all the emotional and painful scenes. The two main males leads, in addition to be very pleasant to the eyes , really brought life and charisma to characters that could have felt otherwise very thin on paper.

The filmmaking was beautiful: it made very vivid the feel of the 1999 era with the big switch from the 20th century into the 21st century. I enjoyed the music as well, it was totally fitting the story narrated.

I would recommend this to people looking for a youth romance both painful and healing and that will for sure provide you a nostalgic throwback feeling. If you enjoyed movie such as the Japanese "Orange" or the Reply series (1997 / 1994 / 1988), you will likely appreciate a lot this film.
