Although it was intended as the main storyline of this series, personally I wouldn't watch this drama for 2 main reasons:

1. The toxic relationship between the male and female lead
2. The amount of ? moments in the drama that kinda make you go huh?

Unfortunate to say, but I did finish this series only because I was hoping for it to pick itself up at the end but it didn't so it was relatively disappointing.
The utter tyrrany, manipulation, obsession, corruption and toxicity radiating from this series is just not healthy and it's definitely hard to preservere through the drama knowing that it's there in every episode.

Overall, I wouldn't recommend the drama if you're looking for a healthy and lovable one although, if this is your kind of trope, by all means, it's possible one of the best ones in that category.

Happy Binging!!
