Great sport-focused drama about the life of top athletes. Drama focuses a lot on the different aspects of training, and the people don't really do much outside the skating training place (which is quite realistic). Many people have ambitions to make it, but in the end, it is a combination of luck, skills and timing that determine who can be the top athletes. The story is well constructed, but nothing special. Trajectory of main lead is also very cliche and predictable. The story is mostly carried by the conversation between people.
The acting is really strong, especially the cast of the earlier timeline. I really loved many of the "side" characters as well, character development is really good here, wish we had seen even more of some of the athletes' background. The story is a bit complex and slow in the beginning, but after a few episodes you will start making sense of every connection between the past and present. It also ramps up and becomes better the second half (surprisingly for a c-drama). Would recommend to watch.
