Hongluancuo's Sister Calls Me Sister-In-Law

There are a pair of sisters in the down-and-out aristocratic Su family: the elder sister is a pearl and has been favored by the whole family since birth; the younger sister was born "unlucky" and was left in the countryside for eight years before returning home. The prominent upstart Shen family has a pair of brothers: the elder brother is the pillar, and stability and reliability are the hope of the family; the younger brother is a playboy, and is considered the black sheep of the family. Two parallel lines that originally did not intersect have crossed and become misplaced. My sister married a cold-faced brother, and my sister married a playboy brother! The elder sister is not an elder sister but a younger sibling, and the younger brother is not a younger brother but a brother-in-law! This relationship was a thorn in the side from the beginning. Family resistance, family status gap, identity dislocation... Is all this the beginning of misfortune or the beginning of happiness?
