The show starts of okay, with a decent story in a refreshing setting.
Most of the characters and story continue like that, with a not amazing but nice progression.

And then there is the Male Lead ( the character, not the actor. The actor is perfectly alright).
He starts of on the wrong foot, sith various actions towards most other characters that are generaly dislikable and bad. But it thought that he might just have a rough patch at the start of the drama, especialy as it's hinted/shown that he is under external pressure and stress. But every episode that i watched he didn't get better, instead he grew worse.
He treated the FL like shit, which was bad but acceptable at the start when they were strangers. But then they started to grow closer and get to know each other, and he kept treating her worse and worse. Same with other characters.
And the stress excuse kept getting thinner as well, as the show depicts him getting time to relax in the countryside and kalm down. Yet his behaviour didn't aprove even the tiniest bit, quite the opositte.

I decided to drop the show when i watchdd the show and it suddenly occured to me that the best, most enjoyable scene that could come next would just be the ML getting hit by a car and dying, or something similar.

TL;DR: in all my time watching western and asian shows, this is only the second time ever where i actively wished the ML ( character, not actor) would just die. I rarely get that level of obsolute disgust, dislike and spite from villains, and they're supposed to be the bad guy. The ML should never be this disgustingly despicable.
