Su Wan, the only daughter of the Su Medical Group, has concealed her true identity for seven years. During that time, she has supported her boyfriend, Lu Shi, through his doctoral studies and helped him establish a home. She has also paid his younger brother's mortgage and covered his mother's expensive medication. One evening, while pregnant, Su Wan attends a family banquet, intending to announce her happy news. Instead, she is humiliated by her future mother-in-law, Zhang Hongmei, ignored by her fiancé, Lu Shi, harassed by his younger brother, Lu Qiang, and framed by Gu Man. After enduring one insult after another, Su Wan finally snaps during Lu Shi's celebration banquet. She knocks over the champagne tower, ends their relationship, and walks away for good.
