For five years of marriage, Sophia Su has given her all without a single complaint--raising their child, showing filial piety to her parents-in-law, and giving Lucas Lu all the personal space he needs. Yet her selfless devotion only earns her a husband who has taken a mistress outside. Desperate to win back her estranged husband, Sophia decides to have a second child, hoping for a baby boy. She naively believes that Lucas’s willingness to have another child with her is a confirmation of her status as Mrs. Lu. But the harsh truth is that Lucas shows up at their home with his mistress. Heartbroken and disillusioned, Sophia finally makes up her mind to let go of this humble and unworthy marriage.
