When Jin Xin, the daughter of a wealthy family, found out that she was a "fake," she didn't cry. Instead, she quickly calculated the optimal solution - leaving in style with the shares and real estate, kicking her scumbag fiancé away, and remaining calm throughout the whole process as if she was dealing with someone else's business. After the real daughter Jin Beibei returned, she was tricked by her rival family due to her lack of common sense and almost ruined her own business. Jin's father had no choice but to invite Jin Xin back to be his sister's "tutor". From then on, Jin Xin started a hard-core teaching mode, tearing green tea with his hands and outsmarting his opponents. Not only did he teach the real daughter to become a qualified heir, but he also won respect and love in the confrontation with the boss.
