The talented teenager Bai Yufei is a figure skater with innate talent and superb skills. He has emerged in the ice arena at a young age. However, his luck is always a little bit short, and he can never get rid of the title of "Millennium Runner-up". At a press conference after a loss, Bai Yufei suddenly unilaterally announced his withdrawal and would no longer participate in the 2022 Winter Olympics. This news caused an uproar, especially for fans Lu Xiaoying, who really did not understand the idea of her idol. By chance, Lu Xiaoying approached Bai Yufei, took care of his daily life, learned about his unknown past, gradually opened his heart, and regained his confidence in the Winter Olympics. Just when Bai Yufei returned to the arena, Lu Xiaoying, who had always been positive and optimistic, fell down. Bai Yufei then knew that this "little sun"-like girl had long suffered from ALS, but had always warmed herself with love.
