Reborn after being murdered by the fake daughter in a wealthy mansion, ten‑year‑old true heiress Vesper returns on the exact day she was sent home, with only seven days before her grandfather signs a three‑billion‑dollar family trust. Surprisingly, her whole family can secretly hear every thought inside her head. While Vesper plans to gather solid evidence against the manipulative Sloane without knowing her inner voice is exposed, her parents and siblings hide this strange ability. They follow her mental hints to block deadly traps, collect proof, and race against time. As frame‑ups, poisoning attempts and life‑threatening accidents keep happening, the whole family must lure Sloane into confessing her crimes before the powerful grandfather arrives and finalizes the trust document.
