In the studio on a snowy night, Shen Nian clutched the broken lead and looked at Lu Zeting, whom he had been secretly in love with for six years in his sketchbook - but on his cell phone, his engagement photos were so painful that his eyes hurt. Childhood cold violence and isolation on campus made Lu Zeting her only "light", but now this light shines on others.
In desperation, she found the "Wenxu Doll" shop in the old alley, handed over the orange candies and Lu Zeting's old pen that had been hidden for five years, and detailed his light brown soft hair and amber eye tails, and customized a life-size doll "Aze", which she regarded as the sustenance of her obsession.
Unexpectedly, the doll filled with sincerity would awaken: Aze stood in front of her when she was scolded by her mother, handed her hot milk when she stayed up late, became depressed when mentioning Lu Zeting, and when Lu Zeting turned around to entangle her, he knocked her parts and said, "Don't touch her." From a substitute to the only one, he used clumsiness and gentleness to break down her disguise and heal her wounds.
When Lu Zeting's true identity was exposed, Shen Nian faced up to the trauma and realized that the person he had customized was not a substitute, but someone who loved her wholeheartedly. Later, she took over the key to Wen Xu's shop, and she and Aze guarded the warm light of the old alley, making dolls for people who came with obsessions - just like when they were caught in despair, they became the "light" for others.
This is a story of obsession and healing, and it is also a two-way redemption across "human and non-self": the best love never looks up to the sun, but someone brings exclusive warmth into the cold winter, saying "I am not a substitute, I am the Azze who loves you."
