In order to save money to treat his seriously ill father, Cheng Cheng (played by Wang Sisi) gave up the opportunity to study abroad. But in order not to disappoint his father, Cheng Cheng lied to him that he was studying in London. In order to make this lie come true, Cheng Cheng found Kan Zi (played by Jaycee Chan), who was good at video post-production. She hired Kan Zi to pretend to be her boyfriend and help her forge videos and photos to create the illusion that she was studying in London. Kan Zi's superb skills deceived the old man's eyes again and again, but in the process, Kan Zi gradually developed a good impression of the kind and strong Cheng Cheng, and treated the old man with true feelings. Unfortunately, the old man's condition worsened and he eventually passed away, which meant that the cooperative relationship between Kan Zi and Cheng Cheng was about to come to an end.
