Everyone at the scene joins in the teasing and laughter, leaving Xu An utterly humiliated. She finally sees Shen Lang for who he really is and decides to cut all ties with him! Back then, Xu An had been accepted into a better university, but gave up the major she loved just to stay with Shen Lang. Now, she decides to withdraw from school and pursue her dreams all over again.
