Lin Cai'er came to Jiangnan, ran a silk shop, and lived a vibrant life hand in hand with her partners. A southern tour reunited the emperor Xie Xuan with her. While past memories were yet to be recalled, a familiar figure and a bowl of sweet-scented osmanthus soup made his heart beat once again. From the water alleys of Lin'an to the courtyards of the palace, the two rediscovered each other as they got along, gradually understanding the meaning of sincere heart and respect. Cai'er managed her business wholeheartedly, and Xie Xuan expressed his sincerity through actions, thus continuing a bond and ushering in a wonderful new chapter belonging to each other.
