Mainland girl Murong Bi (played by Wang Yijin) and Hong Kong boy Ling Zhinan (played by Huang Kaijie) met on the southern coast of Taiwan and fell in love, but they separated because of misunderstanding. Many years later, Murong Bi, who had a bright future, was forced to successfully implement the project within a deadline due to business negligence. For this reason, she had to agree to the request of her cousin Yuan Xiaohui (played by Qian Boyu) to sell three things: love, soul and body without violating social moral norms. During this period, Ling Zhinan came to Beijing for some reason, but unexpectedly met Murong Bi. Will the two rekindle their love because of the memory-filled "Sky of Pearl Island" and face the real answer to their breakup together?
