I'm really curious about why he hates his wife family and what really happened in the last life.
I wonder if in her last lufe her aunt's children hated her. I hope she can talk with her aunt because I feel the twin's father is putting them against their mother and we can see she loves her family. Was he using her for vengeance?

SPOILER
Aunt’s husband is really just an ass. There’s not much to his character that explains why he’s as terrible as he is, it’s probably just who he is as a person. He cheats on her, and wants the power of her family to become his and his kids. As for the twins, it’s mentioned early in the manhwa that they never really interacted with Tia in her past life. They were just indifferent.
I APPLY TO BE TIA'S AUNT'S NEW WIFE SINCE HER HUSBAND IS PROBABLY A DICK, HER SONS ARE A NATIONAL TREASURE, SHE'S A QUEEN, AND I'M IN LOVE.
