The story will be strangely sweet to the idealistic, but far-fetched to the realistic. Nonetheless, I enjoyed the plot, as unlikely as it may be in real life. The writer and production team produced a film that started out a bit grim and ended on a happier note. P.S. Partner stands for Phone Sex Partner (it's not a cute and cuddly film, so children beware!) and as the title suggests, there are some quite erotic moments and flashes of nudity. He he he, but coming from an American TV show background--this much was nothing. ^///^ To me, this story was not philosophical or deep. Rather, it seemed like a hopeful message to anyone stranded by undesirable relationships (u will know what I mean once u watch!). THE BEST part of this entire film was when Ji Sung, the main lead, sang the OST "Show Me Your Underwear." That was a great song, LOL. Anyways, don't decide anything yet before watching this film! It probably won't seem like a masterpiece, but it definitely is enjoyable--and it won't only be for flashes of porn alone.
