My little sister Willa? Always played the noble princess—even during the freaking apocalypse. She was pregnant and still trying to look like some graceful queen. I told her to end it. Safer that way. She slapped me. "Shut up. How can you be so heartless?" Meanwhile, I skipped meals so she and her rescue-pet gang could eat. When I collapsed from hunger, she snorted. "Drama queen. Think of it as a free weight-loss plan." I dragged her to the base, the safe zone, and nearly died doing it. She snatched the last of my rations. "The baby and I are good. Give the rest away." I died from my injuries—frozen, starving, forgotten. Willa? She got crowned a saint. Even landed the baby daddy—the Deputy Governor—and kicked off her perfect little fairytale. Then I woke up. Back to the moment she asked me to swear I'd protect her and the baby. This time, I laughed in her face. "Die for all I care."

I have been the Donna of the Smith family for nine years— but only in name. I took my deceased twin sister Lily’s place, raised her daughter Emma as my own, and lived beside a husband, David, who never once looked at me with love. For nine long years, I gave everything. Emma, however, only saw me as the woman who “killed her mother,” never knowing it was Lily who stole my marriage, my identity, and the man who was supposed to be mine. She pushed me in public, screamed that I was a murderer, and even used the gun I gifted her to shoot the only thing that brought me comfort—a tiny bird I’d been nursing back to health. And David… David, the man I once loved with my whole heart, couldn’t hide the coldness in his eyes. Every time he looked at me, I could feel Lily’s shadow standing between us. So I made a decision. If this family wanted Lily so badly— then they could have her ghost. I would leave the Smith estate, the title of Donna, the child who hated me, and the man who never wanted me. But the night I packed my bags, David suddenly appeared in the doorway, blocking my path— his eyes no longer cold, but afraid. As if he had finally realized what losing me truly meant.

My sister, Aria Sawyer, stumbled drunk into a billionaire's room one night. Now, she was pregnant and wanted the whole family's advice. Something about it felt off.

She decided to end the pregnancy and start fresh. But the very day she left the hospital, headlines exploded. The billionaire was marrying another woman carrying his child. Aria went mad with jealousy. Right in front of our parents, she grabbed a knife and stabbed me to death. "This is all your fault! That spot in high society should have been mine!" And then, my eyes opened again. Aria sat there, blushing sweetly, calling a family meeting. "I think I might be pregnant with Mr. Moore's child. What should I do now?"
