The Whole Internet Is Waiting for Me to Fall, but I Ended Up with My Rival

A washed-up supporting actress gets flamed across the internet and is forced to appear on a "Divorce Observation Variety Show" with her top-tier star rival. In reality, they're a contract couple. The whole country waits for her to get exposed, but then she outcooks the judges, casually fixes the show's broken camera, and has a song she wrote on the spot become a hit when the top-tier star sings it. Her secret identities come to light one after another. The male lead appears to keep his distance, but in truth, he protects her at every turn.
