Yiiiiiikes. I watched up to episode 25, read the spoilers in the comments, and decided to just skim the last three episodes. I am VERY grateful for the commenters who saved me from watching the rest of this drama.

I enjoy these sorts of melodramas with love triangles/squares, revenge plots, business rivalries, family secrets—a lot of dramatic twists and turns—but it's because there's at least one redeeming part of the drama, usually the romance between the leads. In this drama, there's really nothing redeeming. The relationship between the two leads is fleeting and flimsy; she's the overly kind-hearted, self-sacrificing female lead who you end up pitying, while he's the calculating male lead who over and over again makes choices that hurt her, but in his mind he justifies it has having "no choice", owing someone else, or that his choice is what's best for her, too. Even up to the point I had watched, I was already rooting against him, and it only gets WORSE. The female lead says so herself at one point: she is constantly being used in other people's schemes and plans, the only person kept in the dark about what's truly going on. I was almost rooting for the second male lead instead, but he essentially treats her the same way.

The way this drama ends doesn't feel earned, and I truly despised Tang Guo Er. I would only recommend this if you are looking for a dramatic plot without caring about any of the characters.
