@VaguedelOuest no, that's wrong. We don't hate him because of him being evil, we hate him because he has feelings for his own little sister. Not normal romantic feelings, but he wanted Penelope to stay in the palace, do nothing but sit and listen. That's what Derrick wanted. That's also why he had that bird who had the same color as Penelope's hair. The bird was caged, right? That's how he wants Penelope to be. Also, Derrick not only has feelings for Penelope, he also pushed every single problem on Penelope, without even listening to her side of story. He made her to a villain.
We ALL hate red flags, yes WE all somehow like one of them, YES we all are colour blind and YES, we are all a simp for yaoi/Yuri character ✌🏼
