She transformed into an arrogant and capricious young lady who loves to bully the male protagonist, constantly provoking Xie Xun. However, as they got along, Chi Yan gradually fell in love with Xie Xun, and Xie Xun also developed a different kind of affection for Chi Yan amidst being "bullied" again and again.
