For three years of marriage, Ye Shuning is left at home by her husband's family every Lunar New Year's Eve to keep watch over the house, while she watches helplessly as his 'adopted younger sister' moves into her home. In the third year, she stops compromising and sells the marital home registered in her name. When her husband and his family return from Thailand, they discover that the locks have been changed and their luggage has been thrown downstairs. Through hard work and self-respect, Ye Shuning gradually rebuilds her life and ultimately becomes her own safe haven.
