Reborn to Steal My Mafia Husband's Mermaid

I died alone in my mafia husband’s basement, then woke up on the day he captured a beautiful merfolk. Matteo planned to make the creature choose a female form and become his perfect woman. Disguised as a maid, I earned the captive’s trust and promised him freedom. But when the full moon triggered the Choosing, my husband didn’t get the mermaid he expected—he got a powerful man determined to protect me. Now Matteo wants revenge, my mother is being poisoned, and I’m ready to destroy everyone who betrayed us.
