Two old friends, getting on middle-aged and separated for unclear reasons, reunite at lunch and a series of further meetings, reminisce about the old days. They are a natty, complacently married, professor, Munto, and a leaner, more intense film maker, Hun-joon. They talk about an old girlfriend of Hun-joon's, Sunhwa (who seemingly Munho also had an affair with). Various tensions rise up in sudden flashes breaking the calm surface of renewed friendship. Eventually the two go to find Sunhwa, who now works as a bar girl (or manager of a bar), and go back to her apartment for a night of drinking and revelry. Afterward, Munho runs into some students, is cajoled into more drinking with them. Without, hopefully, giving away too much that's about it, and we leave Munho standing on a dawning street, waiting for a cab. Incidentally, there is a good deal of obsession with sex, mostly neither interesting nor titillating, including a scene or two approaching soft core status.
Much of the story is told in flashbacks (or fantasies or dream sequences or ...), and given that not a lot of effort seems to have been made (via makeup or whatever) to distinguish the 20-something flashbackees from the current 40'ish (at a guess) protagonists, it is sometimes difficult to tell which is which. Another viewing would certainly clarify some of what is going on, and I certainly enjoy films which challenge one to untangle every nuance through repeated viewings (see my reviews of "Fallen Angels" (Fallen Angels) and "Flower Island" (Flower Island), for instance). But one has to care enough, about the characters or the film itself, one has to sense that there will be something added beyond, say, simply getting the chronology straight, to make the investment of time and effort, and I couldn't get up the enthusiasm on either count, so returned it without a second go. The two men were stereotypical male jerks, the women basic dishrags, with no seeming commentary about it. It's not an awful film, and maybe I'm missing out, but I just couldn't get into it enough to bother getting into it enough
