Lin Xiao's life fell apart in a short period of time: her mother was seriously ill and hospitalized, her work project was in a deadlock due to changes in her partners, she was criticized and complained by her bosses and colleagues, and her boyfriend who had been in love for many years also broke up cruelly. In this darkest moment, she returned to her hometown town, hoping to find some solace, but she didn't expect to meet someone who would change her life.
Here, Lin Xiao meets the little girl Youyou. Youyou is innocent and kind, full of love and curiosity about the world. During the days spent with Youyou, they chased each other in the fields and played by the stream. Youyou's optimism and positivity are like a ray of warm sunshine, slowly melting the ice in Lin Xiao's heart, making her begin to re-examine life.
At the same time, Lin Xiao used his professional knowledge to help small town handicraft stores expand online sales. While reaping the rewards, he also felt the warmth and support from the people around him. With the help of Youyou's infection and the town residents, Lin Xiao's life gradually turned around. Her mother's condition became stable and her work projects became brighter.
"When the Warm Sun Falls" tells the story of Lin Xiao who was at a trough in life. Thanks to the appearance of Youyou and the warmth of the town, he healed himself step by step and regained hope and courage in life.
