There are better K-dramas out there. Won't recommend watching this drama. But if you're curious why, I'll tell you why.
1. I don't feel the chemistry between the main leads. It's confusing till the end whom the FL going to choose. So both men receive lukewarm feelings from FL.
2. The villain seemed mysterious at the beginning but once we unravel the truth it got boring. The way the villain was caught was way too easy, like how did she even manage to kill so many people and be so mysterious for so long?!
3. The storyline/plot is ridiculous.
4. Too many cheesy and cringey moments.
5. The ending was stupid, using a public bus? What is this a comedy show suddenly?

I could probably keep going but I doubt people would waste their time reading till the end, so I think I made my point. Don't waste your time on this drama. I hope this can help people to not suffer through this drama. :D
