A surprisingly good show. The reason I watched was from a recommendation, I wouldn't have chosen it myself, but I'm happy I did.

The Story: simple but satisfying. Cheating between friends and exes, and how to live after all that. Terrible in real life, great for entertainment value. What stood out for me that it was all believable. Nobody behaved in a way that makes you doubt the script-writers sanity. All the characters felt like real people. Because the whole thing is quite short, not everything was fleshed out as well as it could have been, especially the end could have used another hour or so, but overall it was a well told story.

The acting and cast was superb. None of the actors were on my favorites list, but all the characters were portrayed really well. One of the bad guys ( Shin Jae Hwi) did such a good job that I'm a bit worried I'll hate him when he's in something else. The female leads did great, the women they portrayed were far from perfect, but you can't help feeling for them. I especially liked the style in which the series was shot, not over-done, but the whole series felt a bit like 'french cinema'. The attention to detail, like applying lipstick as almost female body armor, made it a joy to watch.

The Music: this one is a bit harder to judge. The score always fit the scenes, and was even part of the story. Unfortunately I did not like any of the songs, so a seven out of ten maybe?

Rewatch value; I'll probably watch it again. The vibe of the show was really good, but it's not a complicated story with lots of details and / or layering, so it's not something you can watch over and over again.

Overall, recommended if you want to watch a shorter series, that shows real women, trying to solver their own issues, beautifully shot, with a well-integrated score.
