Shen Zhiwei is the daughter of a talented scholar. After her father's death, her family fell into decline and she was married off to a son from a poor family. Not smart, not pretty, not kind. The advantage is toughness - like weeds, they cannot be trampled to death. He can scheme, lie, and pretend to be pitiful, but the bottom line is "don't harm the children." Xie Heng comes from a poor family. He looks as gentle as jade, but is actually cold and ruthless. The purpose of taking the merit test is to investigate his father's unjust death case. To the heroine, she initially said "cooperate to live together", and later said "this person can't die".
