My Letterboxd review with some minor tweaks (short because this show killed my will to live):

the webtoon did not deserve to be brutalized like this.

seol isn't unpopular in the webtoon lol idk what they're talking about here. and as much as i love seol's actress, this role wasn't right for her. baek inho (actor and character) served though honestly.

I would also like to add on (post-reviewing on Letterboxd) that the acting, as a whole, was good. People put work into this drama and I can tell and appreciate that. It's just that this show completely disregards the feeling and direction of the source material. If I wasn't such a big fan of the Webtoon, I doubt I would have finished this at all.
