But it's actually true that perez caused the downfall of the emperor and empress in tia's last life. She just didn't know how he did it that's why she didn't intervene much. Remember when she found out that the company competing with them for the logs was owned by perez? Yeah that's how she realized how he started gaining power and that's when he went to the academy. It's actually good of her to let perez do his own thing instead of helping him because she knew perez is capable like that. He's just moving more comfortably now compared before because the lombardis have his back.
My theory is it was your dear Perez who caused the fall of his father in last life after being granted crown prince title. Bro had to avenge his mother.
