On the eve of the wedding, He Shiyan's fiancée, Xi Muxue, repeatedly sacrificed their wedding venue and wedding planning team, and even ignored his taboo of mango allergy, all to accommodate Tang Yu's comeback tour, indulging Tang Yu in damaging his custom-made wedding suit. At the celebration banquet, Xi Muxue forced He Shiyan to drink wine containing mangoes. While he suffered a critical allergic reaction, she only cared about the injured Tang Yu. He Shiyan died completely in heart, quietly quit his job, cut off all contact, and went far to Boston to engage in scientific research. Xi Muxue belatedly chased abroad to win him back, but He Shiyan explicitly stated that their relationship had long since ended. In the end, Xi Muxue returned home disconsolately, while He Shiyan started his own new life in the foreign snow.
