Although Song Ting had a cold personality, his experience as a doctor exposed him to a wide range of emotions, making him quite adept at understanding human nature. So, he could sense Song Yin's expectations.
This implied that the event held substantial importance for Song Yin, and Song Ting was eager to uncover the underlying motive.
Song Yin regretted seeking her elder brother's help. She lacked the audacity to deceive him. In the past, her approach was to cry and manipulate situations, making it appear as if Song Fan was bullying her. However, she was hesitant to lie to her older brother directly.
She then immediately started crying to stall for time. Eventually, she said, "Lately, everyone has been saying that I'm not a true member of the Song Family because Sister is the true daughter of the Song Family. Attending the banquet with you will put an end to these rumors, and no one will say such things anymore."
