Almost every episode was touching in some way and often addressed topics not generally talked about or shown in dramas. Of course, there were episodes far better than others and all the episodes had their own problems that were either entirely obvious or just a bit noticeable.

If you were to ask me which ones you can skip?
-Honestly, it would probably just be Ep 7. I found the others beautiful in one way or another and was very glad to have seen them, and I rewatched them. I doubt I will for Ep 7 though as it was really just okay and the plot didn't feel new or highly emotional.

Which ones are a must watch?
-That's kind of tough. If you forced me to pick, I would say Ep 1, Ep 4, Ep 6, and Ep 2. It's really hard not to pick Ep 3 or Ep 5 as well though. Ep 3 is a difficult pill to swallow though which is why I wouldn't recommend it for most people. Ep 5 was basically on par with Ep 2 but didn't tackle the important subjects it did, but it had much more heart and realness than I expected it to.

Really, this is the kind of drama where you can pick which stories appeal to you the most. There are some characters that appear later in other episodes but there isn't really a running thread. The episodes that are the most connected and will leave you missing a part of the story if you skip either of them are Ep 1 and Ep 4. I'd say give at least one or two episodes a shot, I'm sure there's at least one you'll really like.
