Lin Wei, a sensitive and introverted senior student at the Academy of Fine Arts, is accustomed to self-isolation due to the influence of his native family, and his paintings often have dark tones. By chance, she met the administrator Gu Xun at the community library she frequented - she was once a promising graduate student in the Department of Architecture, but she chose to live in seclusion after her sister died unexpectedly.
Gu Xun noticed Lin Wei who was always drawing in the corner. Starting from the subtle care of handing tissues and repairing pencils, he slowly entered her world. He shared his sister's drawings and encouraged Lin Wei to break through the knot in her heart and lead her out of the cage of self-isolation. Under Gu Xun's guidance, Lin Wei gradually injected bright colors into the paintings and learned to reconcile with the past. The two gradually fell in love during the charity sale of used books, walking together on rainy nights, and the turmoil of the graduation exhibition, and each became the light that illuminated the other's gloomy past.
After graduation, Lin did not sign a contract with an art museum, but faced distant invitations to the Beijing Art Exhibition and reluctance to leave Gu Xun. In the end, she chose to return to her original aspiration, and together with Gu Xun, she transformed a corner of the library into a charity art studio, offering free art classes to children in the community, and passing on her warmth to more people. During this period, Lin Wei and his father resolved their knots, and Gu Xun also got over the haze of losing his sister.
The two made an engagement on a rainy night in the studio, and held a simple wedding in the presence of sunflowers in the courtyard. After marriage, the birth of their daughter Xiaoyang made the family more complete. They took Xiaoyang to continue running the studio and witnessed batch after batch of children finding happiness through art. Ten years later, the studio has become the community's "transfer station of light." Lin Wei and Gu Xun have always joined hands, using love and persistence to write a warm life of "walking towards the light, never stopping".
