What could've been a decent mystery, is dragged down by its somewhat plain and unimaginative arthouse execution. The plot is interesting enough, but Lee drags out every scene to its breaking point. When it works the result is magical, more often it fails and the film becomes unbearable.
Jong-su, an aspiring writer working as a delivery guy, runs into Hae-mi, an old friend. The two hit it off, and he promises her to take care of her cat while she's away on holiday. When she returns she introduces him to Ben, a well off, confident guy who seems to share a special bond with Hae-mi. When Hae-mi suddenly disappears again, Jong-su suspects Ben.
There's an uneasy atmosphere that lingers from the very start. It's pretty clear that something is off, but it's hard to tell what it is exactly. The film itself is also sparse with information and the ending leaves plenty of loose ends. While that's all nice and interesting, the pacing is just too slow and neither the mystery nor the audiovisual qualities are strong enough to cover it up. A bit disappointing.
