This was not good... definitely the worst Kdrama I've seen so far. The attempts at humor just did not land for me at all, and mostly made me cringe throughout.
It was one of those shows where things just happened because the writer wanted them to, with no real justification, buildup, explanation, or even an attempt at a set up. Without spoiling anything, the ending was like the writers gave up and just waved a magic wand so they could finish and go home... you'll know it when you see it. Even though nothing in the show makes much sense (definitely check your brain at the door), they didn't even bother to introduce even a convenient/contrived mystical or poetic excuse for the ending. It just happens out of nowhere... poof... story resolved.
The first half was a chore to get through. I'm used to Kdramas opening an episode with the last scene of the previous episode, but usually you get to see a new perspective, gain important context, etc... but not in this show. Expect a significant chunk of the runtime (and episodes are already pretty short) to be watching an identical scene multiple times in a row. This becomes less frequent towards the end, but it's super annoying for much of the show.
I will say that the last few episodes were decent, and they managed to be enjoyable. The lead actress is great at crying scenes for sure. Wish I didn't waste my time with it though.
