The drama excels in its dialogue and delivery, the acting is superb and the show is hilarious. Several laugh out loud moments additionally several moments where I cried too. I felt for Joogyung and was extremely happy for you when she realised her self-worth and inner-beauty. Story is filled with a bunch of cliches but executed really well.
I would say the drama goes extremely well up until around episode 12, which is why I rated the rewatch value at a 6 because I'd watch it up until then. After ep 12 I no longer felt the hype and would watch the show several days after release. The storyline was a bit of a drag. The last two episodes were disappointing, I'm satisfied with the ending however the episodes were not needed, the pace was off. It felt like they were fitting so many things into the episodes.
OST was alright, it wasn't impactful, didn't add anything to the scenes but some of the songs were catchy.
