My Dear Daughter, Love Me Once More

The male lead only has eyes for his first love and won’t even let Aria, his own daughter with his wife/the female lead, call him “Dad.” Aria waits all day for him on her birthday, only to witness him propose to his ex. At the school talent show, the mistress and her daughter bully Aria, and the husband helps them. To steal Aria’s summer camp spot, he feeds her a strawberry cake, knowing she’s allergic—she nearly dies. That’s when the female lead decides to divorce him and finally reveals her secret: she’s the daughter of a duke. She uses her true identity to fight for justice for her daughter. In the end, even when he kneels and begs Aria for forgiveness, she never calls him “Dad” again.
