Su Zhiyao cared for Old Master Zhou for seven years, only to be forced by her mother-in-law, Luo Xiulan, to leave with nothing because she "couldn't have children and had no family background." The day her husband, Zhou Jiming, silently signed the divorce papers, she finally gave up on him. But when the old man's will was revealed, the Zhou family's core trust, old mansion, and priority rights to its shares had all been left to Su Zhiyao. Luo Xiulan broke down on the spot. The lawyer, He Mingchuan, produced the ledgers, and Zhou Yuwei switched sides to help her. Only then did the Zhou family realize that the daughter-in-law they'd driven out wasn't weak, but the only person who could save them.
