Kang Baek-ho and Ham Yi-seul have been close friends since elementary school. Baek-ho has never recognized his feelings for her, not realizing that Yi-seul has been in love with him for over 20 years. At Yi-seul's wedding to another man, Baek-ho is overcome with regret for never confessing his love. A mysterious conductor appears and offers him a second chance to win Yi-seul's heart. Baek-ho travels back in time to key moments in their lives, hoping to alter the course of their relationship. However, changing the future proves to be more complicated than he anticipated.

Did you or a loved one work on Operation Proposal?
Every stage matters — pitch decks and treatments from development, location scouts and table-reads from pre-production, set photos and crew anecdotes from production, edit-bay notes from post, and press kits, festival memories, or marketing ephemera from distribution. Any moment that didn't make the press tour, any document or photograph that's been sitting in a box — please share it so it's not lost to time.
We particularly welcome contributions from writers, producers, cast, crew, festival programmers, distributors, marketing teams, their families, and anyone who was there at any stage.
