Synopsis：The male lead is obsessed with his first love and won’t even let Aria, the daughter he had with his wife, call him “Dad.” On her birthday, Aria waits for him all day, only to see him propose to his ex right in front of her. At the school talent show, the mistress and her daughter bully Aria, and he even helps them. To steal Aria’s spot at summer camp, he deliberately feeds her strawberry cake, knowing she’s allergic—she almost dies. That’s when the female lead finally decides to divorce him and reveals her biggest secret: she is actually the daughter of a duke. Using her true identity, she fights to get justice for her child. In the end, even when he kneels and begs Aria for forgiveness, she never calls him “Dad” again.
