However, he's also an asshole to other people. Tripping maids, forcing them into cursing their masters after threatening them... Sure, he may be more of an ass to the ML due to whatever may have happened in the past, but he's also in asshole to innocent people.
Innocent people? Pretty sure that maid insulted him bro
She was literally just asking who he was since she had never seen him before and strangers aren't allowed in that area? He also tried to beat up the MC's knight?
Y'all forgetting the part where after the maids question if he should be there, they start giggling/gossiping and insult him by saying he looks poor for a noble. I also understand that he was an asshole to the knight but that's possibly because he's protecting the enemy (the MC who he believes is the real daughter), hence the knight is also an enemy. I'm not saying he's not acting like an asshole. He is, and he shouldn't be treating the MC and knight this way as they've done nothing wrong, but the MC is pretending to be someone who is evil. How could the cousin possibly know it's a fake, and even if he knew, how would he know that she doesn't want to help the family but is actually planning on revenge? All I'm saying is people in the comment section were pretty quick to judge a character who's mean to the MC without considering the situation. Just wait and see why he's acting like this in the first place, he may have an actual reason.
While I get that red haired guy is an asshole he's not being an asshole to the ML for no reason. He's being an asshole bc of something the father and the real veronica did. Knowing what the two of them did to the ML in the past life, we know that they're not good people, thus the cousin's hatred for veronica and her father may actually be justifiable. It's just unfortunate that ML has to deal bc she's pretending to be veronica.
