Zeng Kexin was betrayed and murdered by her best friend, Su Zhouyu, and Su's boyfriend, Li Hao, who coveted her house. Reborn with bitter resentment, she returns to the day the two first came to her home. In her previous life, she treated Su Zhouyu like a real sister, only to have her property coveted and her bank card secretly swapped. Over three years, Su Zhouyu fraudulently spent more than two million yuan. This time, Zeng Kexin calmly sets her plan in motion. She charges the pair for every attempt to freeload in her home, drives them away, keeps evidence of their harassment and slander, and leads Li Hao's creditors straight to him. At a class reunion, she exposes Su Zhouyu's fake identity as a wealthy heiress. Desperate, the two break into her home in the middle of the night, only to fall into the trap she has prepared. The police arrest them on the spot, the stolen money is recovered, and the culprits face legal punishment. Finally free of all her troubles, Zeng Kexin begins a peaceful and independent new life.
