In a remote province, a private ice skating rink that is open to the public when the owners aren't around is located.
On this ice skating rink, some youngsters who are now in their twenties were practicing. However, unlike in the morning, when the ice rink is full of people, there is always one young man named Yun Luan who is always practicing alone. He used to be the regional champion of pair competition with another ice skater named Lei Jun. However, one day, to save his falling twin from a bad fall while practicing, he was injured in the ankle and failed to join the main city competition. Instead, his twin brother Yun Hun took his place and entered the competition with his partner, Lei Jun.
