In his freshman year, Su Nian'an's camera accidentally photographed Lu Zhiheng, the school sweetheart of the computer department who always wore a white shirt and typed code faster than he could talk love. She thought it was just a useless picture, but she didn't know that she had become the only protagonist under his lens.
In the warm light of the club warehouse, he helped her adjust the camera parameters and complained that her "composition was too sweet"; on the cross-campus bus, he gave her the window seat and stood to protect her lens; under the spotlight of the graduation ceremony, he took the photos she took and confessed: "From military training to wedding dresses, your lens chases the light, but my light has always been you."
This is a campus story about "two-way secret love": she secretly collects his tenderness through the camera, and he secretly stores her smile in the photo album. When the sound of the shutter meets the sound of the heartbeat, it turns out that the best love is when we are the only protagonists in each other's world.
