In his sophomore year of high school, Ye Yushi transferred to another school and returned to his hometown to study. On a rainy day, he was knocked down by He Xizhu, who was riding a bicycle. This young man with a guitar on his back and a red string on his hand became her deskmate. He always played the guitar to her when it rained, recorded "When It Rains at Night" into her MP3, and drowned out the thunder with lame jokes. When she was hiding in the piano room crying on the anniversary of her mother's death, he stuffed her with a note: "Xi Chuangzhu applied to be Ye Yushi's exclusive sunny day."
On the eve of graduation, Ye Yushi discovered the admission letter to a famous music school hidden by He Xizhu. She tore up the unsent love letter, pushed him away and said, "I should not be in your future." With red eyes, he tied his mother's red string around her wrist: "When you are no longer afraid of the rain, come to me." In the next five years, the songs he wrote always contained the abbreviation of "Ye Yushi", and the music reviews she wrote always avoided his interview.
25-Year-old Ye Yushi reunited with the finale singer He Xizhu backstage at the music festival. During the interview, he suddenly sang "When It Rains" acapella, and the lyrics were about the unsent love letter from back then. When the rainstorm suddenly hit, she subconsciously touched the red rope, but he held her hand: "Now, let me hold the umbrella for you."
- When he was a teenager, he was her uninvited visitor during the rainy season.
- After separation, she was the rhyme he never said
- When we meet again, those unspoken words of "I like you" finally grow into the brightest sunny day in life.
Concept: Some people are like rain, breaking into life unexpectedly; some people are like candles, gently illuminating all wet corners.
