Most of what I have to say has been said in other reviews. Tor was hands-down what saved this drama. His fantastic acting and on-screen charisma were downright electric.
I don't typically enjoy revenge dramas, so it's not surprising this wasn't my favorite.
The main issues I had with this drama were: 1) the female lead and 2) the stereotypes *gag*
The female lead was honestly completely unnecessary. I think they were trying to go for the "female lead softens vengeful male lead's heart," but I personally did not see that ever happen. He fell in love with her and she tried to tell him to stop his revenge plan, but I don't remember him ever listening to her. Tor just ignored every bit of advice she gave him.
I also didn't care for the female lead's character. She was very vanilla, as most female leads are in lakorns. As a viewer, I was completely indifferent to her.

Now for the stereotypes. Where to begin. There were so many scenes/lines that I saw coming from miles away. The part at the end where he gets pregnancy symptoms for her? That trope was funny the first time I saw it... nine years ago. It's gotten more and more ridiculous with each lakorn that uses it.

This lakorn was worth watching once to see the extremely talented Tor, but was unremarkable in every other sense. I doubt I'll watch it again.
