I don't usually write reviews for shows but I had to after watching the last episode. There's no doubt that this show tells a story differently. It can be difficult to get into if you don't like quieter, carefully paced shows. There are entire episodes which consists of just one scene and dialogue between two characters (similar to that of the book "The Symposium" that Int gives to Wang). Not to mention, many parts of the acting and scenes feels more like watching a live play rather than a tv show. And many aspects (geographical lines, affection and attraction, loneliness) are spoken of metaphorically. All of which gradually builds up until the final episode where everything is so clear in who the characters are, what their "lines" are, and how they go about living. The only score is the song sung by the actor who plays Wang. It complements the show beautifully.
It is a very cathartic and special watch. Highly recommend.
