Two old friends bump into each other, get drunk, and decide to look for an ex, like she's a lost phone charger. That's the plot on paper. What actually makes it interesting is the thing neither of them says out loud — Munho slept with her while Hunjoon was away, and Hunjoon still doesn't know.
Munho teaches art and drinks like it's part of the job. Hunjoon's just back from film school in America, quietly pleased with himself. Between them sits Sunhwa, a woman they've each built a version of, and I don't think either version does her many favours.
What works is how flat the film stays on purpose. It never gets close to Sunhwa's inner life, and that's not laziness — these two have always treated her as an idea rather than a person, and the film just goes along with it.
The trouble is it runs slow, and the repetition tips into padding once or twice. By the time Hunjoon finds out and storms off, it barely registers as a twist. Nobody here was ever thinking about the future. They're circling the past, hoping it'll pay them back.
