Overall, "The One and Only" was a decent drama. I think the crime portion made a mess of the show in the later half which is unfortunate.

Story- It's about 3 terminally ill women moving to a hospice where they get entangled in a murder case and a hitman. I understand why the writer added something else because a drama about people dying is depressing (the show is sad but also has lighter moments. It has a balance of some sort, hard to explain), but the crime took over which I didn't find the greatest. It overtook all of the personal stories of the hospice patients and the bond between the 3 mains. I wish less time would have been spent on the crime and more on the personal stories. The crime case was dragged out and became repetitive so it didn't need the amount of screen time it had. Episodes 9-12 felt like fillers so it slowed the story down as well. Finally, I also thought In Sook and Woo Cheon's moments became repetitive but they were still endearing <3

Acting/Cast- Everyone did a really great job!! The show stopper for me was definitely Ahn Eun Jin, she was amazinggggg!!! I will say I wasn't a fan of Mi Do but I think that didn't have much to do with Joy, more the way the character was written. It's a shame because she had a much deeper story that wasn't really given enough time.

Music- It was good, nothing in particular stood out but it fit the show :)

Rewatch Value- I don't rewatch shows but if I did I wouldn't rewatch this one. It was okay but it's more of a one time watch.

I'm sad the show didn't have good ratings because it wasn't bad at all! I would recommend trying if you're looking for a sad show or love Ahn Eun Jin!
