This drama is (unfortunately) completely ruined for me by its predictability. Nothing shocking or unexpected happens, and I can basically guess everything that's going to happen over the entire length. The only reason I managed to complete it was because it was short, and even then I struggled. I suppose it's a testament to other writers skill that they can avoid this one flaw that manages to destroy the entire show.

Now, I'm not going to discredit the show entirely. I came here for a revenge plot, and I got one. And maybe it's my own overconsumption of this trope that's at fault, so let's take a look at the positives. The premise is solid, and there's little fluff or filler in the series. The story gets down to business quickly and manages to introduce the characters pretty well and efficiently. The protagonist also manages to succeed in situations due to her own skill, which is nice. The music is actually really good in my opinion, and acting is good enough to surpass suspension of disbelief. Unfortunately, the positives end here.

Obviously, the predictability of the show is the biggest problem by far. Every new idea and premise and character that's introduced has a clear and predictable conflict and ending which is followed to a tee. Tropes and clichés are basically all that exists in the drama, with not an ounce of subversion to be found. Also, some of the actions of main character are a tad questionable, and sometimes she doesn't seem to learn from her mistakes. The premise is that she is returned to the past so she can redo life with more experience, but oftentimes her success still relies on luck and those around her. The romance felt pretty rushed as well, and it was sometimes difficult to discern the protagonist's own feelings on either of the leads. She often felt like more of a passive character than a proactive one.

And really, there's not much more than that, but the massive, gaping flaw at the heart of the story is what really ruined it for me. Perhaps if you're not all that familiar with common tropes or you're willing to look past an abundance of them you might enjoy this drama, but otherwise I will firmly recommend against watching this.
