I know many people probably won't agree with me, but I will say what I think despite of that.
I enjoyed the drama, because the plot was brilliant, story twists were really well done and acting was really something, however I felt like romance was totally unnecessary here. I didn't like the romantic part at all, it seriously got on my nerves and did nothing more than this. Don't get me wrong, I 'm a fan of rom and rom-coms on daily basis, just when I was watching this show, romance bothered me to this extent that at some point I actually stopped watching it and recently came back to this just because I was curious about the plot.
