Just because you do like a show, doesn't mean it's not problematic. Stalking someone is objectively a bad thing…
I'll explain my comment differently for you. This isn't just about 'stalking,' it's about revenge, as in a transaction between him and Sangwoo. He believes Sangwoo wronged him and doesn't get an apology, so he makes his own justice. It's transactional. Tit for tat. It's not as one-sided as y'all would love to think. Of course what he's doing isn't right, but it's only a plot device. Again, this kind of transaction is what pretty much always happens in enemies-to-lovers, so maybe this trope just isn't for you.
If you don't like the characters or the plot devices (Jaeyoung pestering Sangwoo), nobody is forcing you to watch it. If you want a drama where everyone shits rainbows and unicorns, go watch Kieta Hatsukoi. (no hate, love that show) However, just because YOU don't like the premise of a show, it doesn't make it bad or problematic. Keep in mind, it is a PLOT DEVICE for enemies-to-lovers. Jaeyoung isn't inherently malicious, he is just getting even. He feels justified in getting petty revenge for not graduating. The whole point is that his revenge was only going to be brief, but then he falls in love and doesn't want to leave Sangwoo's side. That is literally how enemies-to-lovers works. You don't like that trope? Fine. But don't act puritanical. To quote Heroism further down in the thread: 'It's like going to a horror series and complaining about it being scary.'
I'm not really feeling the chemistry that much... It's like Ji Woon was mostly attracted to Hwi's cute/pretty looks and demeanor, while Hwi is just rekindling an old crush. I mean... sure, they're both very honourable and good-hearted and they like that about each other, but it's just not enough to get my heart racing. They don't have banter or a back-and-forth, and if they do, it's one-sided with Ji Woon pulling all the weight with his goofiness.
I don't understand why other people are not as infuriated by the complete disregard for joseon royal palace etiquette.…
I honestly find it relieving that this drama is a bit more chill about that stuff (it really improves their chemistry), and I'm pretty sure real life back then wasn't as rigid as it usually is in historical dramas. Otherwise there would have been no affairs, improper friendships and scandals (and certainly no homosexuals), if noone took the first step in disregarding 'etiquette.' But I do agree that the uncle (and the Chinese diplomat) getting off scot-free was ridiculous.
Moo Young's death was so unnecessary like?? why didn't he just lock the doors and leave. The way he went down instantly was also pretty disappointing. His death kind of reminds me of LOTR when that random elf general has this big Sad dramatic death and aragorn is like nooo and we over here like sorry to this man... We don't know Moo Young and Ha Ram's past or relationship, and we don't know Moo Young at all except he's spiderman/nightmonkey. The writing is just snowballing at this point.
