Encounter in the fragrance of coffee: 26-year-old graphic designer Yan Xiaoyue met financial analyst Cheng Yuan in an independent coffee shop "Waiting for Someone". A heavy rain caused the two strangers to start talking and discovered that their souls fit together.
Sweet dream-building time: The two traveled to every corner of the city in three months. Cheng Yuan gave Yan Xiaoyue an "emergency medicine box" filled with 365 letters on her birthday, and agreed to open one letter every day, becoming each other's strongest support.
Cracks begin to appear: Cheng Yuan suddenly starts to work overtime frequently, mysterious calls appear on his mobile phone, and his attitude toward Yan Xiaoyue gradually becomes colder, but he suddenly becomes gentle again every time she wants to give up.
The truth about Snow Night: On Christmas Eve, Yan Xiaoyue brought Cheng Yuan's favorite chestnut cake to the company, but she saw him embracing his ex-girlfriend Lin Yan and learned that he had been swinging between two women for the past six months.
A decisive farewell: Yan Xiaoyue encountered a car accident while leaving in the snow. After waking up, she deleted all contact information, but kept the 365 unopened letters. Cheng Yuan only realized his sincerity after learning that she was injured.
Misplaced reunion: Two years later, Yan Xiaoyue became a well-known illustrator. At a book signing, she met Cheng Yuan who was wearing a wedding ring. The two looked at each other and smiled across the crowd.
