This drama had so much potential and the first few episodes were great. However, after episode 5 or so, it goes downhill pretty fast.

The story became a mess, they've tried to pack it with too much stuff but never really bothered to actually build the fondation of each part strongly, the romance part being the worst one. I don't mind watching a drama with no much romance, but at least do it properly. It feels forced and/or it comes from nowhere.

As other said, Hee-ju's character doesn't do much and it gets really frustrating. You have a good actress and do nothing more than make her cry all the time? (On an unrelated note, I really don't like the shoes she wears in the whole drama and watching her run in these is even more annoying)

I watch until episode 11 and decided that my time was to precious to bother trying to finish it. The story not only was a mess at this point but they started to drag the plot so much, I couldn't take it anymore. Not the worst drama I watched however, there's still some reedeming qualities here and there, but at some point, I lost interest and didn't enjoy any of it.

My advice, if you still want to try, is to be attentive to how much you're enjoying the show after episode 5, so you can drop it early if needed unlike me who tried until episode 11 for no good reason.
