The Koreans do wonderful work in romance, fantasy, and time slip, and this film also combines the Korean sensitivity with portraying children and young people. Even so, the film has twists that move it beyond sci-fi and more into explorations of time, love, devotion, sacrifice, and more. Also, the writing, direction, and actors are all excellent, and I was swept in from the beginning by the relationships between the kids, and then the two leads' sensitive portrayals of their characters in a difficult transition within the story. My only reservation is the ending seemed rushed, which can be an issue in some Korean films and dramas, but it does work...just a bit flat IMO. Still, I do strongly recommend this little jewel.
