When wedding planner Lin Wan was sorting out client information, she found a yellowed love letter signed to her in the folder. The handwriting was exactly the same as that of her fiancé who died in a car accident. As ten undelivered love letters appear one after another, she follows the clues to an old-fashioned photo studio, but the owner claims that the letters are from "senders in parallel time and space..."
Purpose: "Love is learning to let go of eternal regret, rather than tampering with fate."
