I met Momo through a friend after starting my career, and we married after two years together. One day, she attends a college reunion for the flashy club that used to organize barbecues and snowboarding trips—a side of her that is hard to reconcile with the refined woman she is now. A video from the after-party shows a man standing suspiciously close, apparently her ex. “I’ll be home by ten!” a drunken Momo promises, but after that video she stops responding. As my anxiety grows, I cannot stop wondering whether she is with him.
