Are you Joonwoo?
You sound like Joonwoo.
I would expect you as the reader to be able distance yourself from the story and see the bigger picture, not think on the same level as one of the characters.
Lila never intended to help Joonwoo, she was just using him. Anything Joonwoo got out of it was entirely UNINTENTIONAL on her part. Go reread her arc, specifically chapter 51. Everything she did was done with the intent of hurting Joonwoo not helping him. Just like every other guy before him. Quoting her ex:
Those words... do you really think you were the only one to hear them?
...
She actively seeks out broken guys like us
On top of that she showed no remorse for her actions. The fact that she ended up helping him grow doesn't make her any less of a shit person.
And you talk about taeyang, but you need to remember he was beating up junwoo for 2 years, making his school-life a nightmare, it's not something he can easily forgive.
And we now know that was a really fucking unfortunate misunderstanding between them. How would you react if you thought a close friend had betrayed you the way Taeyang thought Joonwoo betrayed him? Obviously the bullying wasn't cool, but it's not like he was doing it for nothing (from his perspective).
Again, Taeyang was the one who came to Joonwoo's rescue after
LILA set him up to get his ass kicked. Are you just going to ignore that? I never said he had to forgive him, just make an to effort patch things up. There is no reason for them to be hostile towards each other anymore.
Lila, on the other hand, has done nothing to deserve forgiveness; she's the same person she's always been. Joonwoo's just giving her a (pussy) pass because she's pretty girl and he want's to 'save' her.
