I don't get how this is still rated so well. For me it's one of the worst dramas I've ever watched. Don't get me wrong, it´s not incredibly boring like some dramas tend to be and neither is it of really low quality or hard to follow. It is however incredibly toxic in my opinion, most of all the 1st male lead is. The guy is seriously twisted in so many ways and I really cannot believe the female lead actually ends up with him. There's more things I found toxic in the drama, I don't wanna go into too much detail though. So while some people might've liked the story and probably didn't think too much of the toxicity and abusive behaviors of some characters, I think this drama should be watched with caution as it might be triggering for some people. I would personally recommend just skipping this one though, there's so many way better dramas out there (hmu if you need some recommendations). The only reason I finished was because I got invested in the 2nd male leads storyline, who was the only person I kind of liked in the drama. But of course like most of the time, the nicer guy doesn't get the girl....
(Apart from the male lead, I did like all of the actors btw but that didn't save the drama for me)
