Lin Wan and Cheng Yi met in the comment section of the King of Glory video because of the sentence "Yao is so difficult". From game teaching to daily "morning and good night" companionship, the two agreed to show up in 900 days. During the 900-day countdown, they shared their lives and exchanged secrets across the screen. Cheng Yi used extreme care to heal the sensitivity and uneasiness caused by Lin Wan's native family. After finally meeting and living together, the two of them were building a blueprint for the future in a rental house. However, Cheng Yi died unexpectedly on a snowy night. Lin Wan fell into the cold winter without him, relying on memories to keep warm in the frozen time, and finally learned to carry the love he left behind, and learned to live again in the loss - it turns out that the coldest winter is the eternal spring in the bones of those who have been deeply loved.
