Summer Blue Hour

Li Zhen returns to his coastal hometown after a decade away. In his hands is a key to the old lighthouse—his father's final instruction was to open it only in case of absolute necessity. Meeting his former love Xiao Yu leads to an unexpected discovery: she has been keeping letters Li Zhen believed were lost forever. This 2025 drama explores memory's fragility and how the past persists in the smallest details of the present—the scent of salt on the wind, cracks in old photographs, unspoken words between former lovers. The film balances nostalgia and painful truth, forcing its characters to reconsider everything they thought they knew about themselves and each other.
