Zhang Wenkai, a new insurance industry executive from Taipei, was inquiring about his delayed luggage at the airport when his coat containing his engagement ring was taken away. Wenkai went to a jewelry store to buy another ring and happened to meet Wu Hanni, a customer who loves apples. As he was sensitive about apples, he avoided them. However, Hanni asked him to pretend to be a couple in order to get a couple discount in the store. The two barely managed to get through the interrogation of the jewelry store manager.
