In summary I thought the plot was clumsy and ill conceived.

I feel like 80% of it is taken up by people traveling to other destinations to threaten another person, and then all of those people have to travel to another destination to talk about it and repeat.

Also they keep styling her like an elderly teacher from the '80s. She has some of the most ugly outfits that I've seen on a K-drama. The frumpiness is unrelenting.

For the most part the actress has a worried furrowed brow expression, and it becomes so repetitive. The dynamic becomes repetitive. The fact that she continually makes things worse for herself she never plays it smart not harder. She always plays it harder and not smart, it becomes agonizingly frustrating to watch.

They provide a little backstory on some of the antagonists, but not enough for some of their motives. What is the matchmaker ultimately trying to accomplish as she runs her business into the ground, for what? What is the attorney using all her embezzled money on? Why is she so upset with Kang Nam-Sik for mentioning marriage when she's the one who bought him a ring? And it is unforgivable that Seo Hye-Seung had that phone the whole entire time and only got it fixed at the end.

I felt like the kids delivered really solid performances though. But that's not enough to make the whole thing palatable.

There are better revenge dramas out there, this one is just not fulfilling.
