The innocent and lovely Xin'er longed for her first love. She met her prince charming, Mu Heng, in the restaurant where she worked part-time. Mu Heng was as gentle as jade and a handsome gentleman.

Ou Yiyang ignored Li Lu's objections and used his strong financial resources and influence to create many misunderstandings between Xin'er and Mu Heng. Between friendship and emotion, Li Lu reluctantly chose friendship, while Ou Yiyang married Xin'er as he wished.
