Ye Wanqiu, the eldest daughter of the Ye family who returned from studying abroad, was unwilling to follow the family's arrangement and marry into the Zhou family. She packed up her things and ran away from the marriage overnight. The Ye family had no choice but to ask the second daughter Ye Wanning to marry her on her behalf. From then on, the two sisters began to lead different lives. Women exist not to please men, but to please themselves.
