I think the plot itself was good. The actors did fine.

I was expecting a contract/forced marriage to gradually become a fluffy romance. Not what I got.

The ML actor was good looking but the character was a major turn off. That character has some serious mental issues. He was obsessive and abusive to the FL. The scattering of sweet moments did not make up for this. The dichotomy of those moments made it all the most disturbing. This might have been compounded by binge watching it in one sitting.
