This way we will also be able to pull the layers off iseul's character cuz before the arrival of Seonwoo we knew a very little of Iseul's personality. We as readers only saw her through Sori's eyes now we will be able to be see other's perspective of her too. So yeah people who are disliking Seonwoo are correct too but it will be beneficial for you to see her not as an antagonist but a major plot point who can move the story forward.

Yeah you're right the way people are hating her is only proving that she is significant to the story if her character was boring no one would've paid so much attention to her in the first place. You know how people say that it's guaranteed that an actor is doing a good job if they have the ability to make the viewers like or dislike their character so much that it starts affecting them personally lol....in this case we can say the author is doing great work to make Seonwoo's character interesting and adding depth to her (:
Is it wrong that im sorta, maybe, slightly, subtly, in a very minuscule kinda way might be rooting for the ex?
Sori is still endgame for me but I mean....a throuple wouldn't be so bad....right....right???
