Ah Lei (Bolin Chen) is the younger brother of Stone, a guitarist of Mayday (Taiwanese band). He is also the administrator of Mayday's fansite, in charge of replying to fan letters and emails. One day, he befriended a girl named Zhao Xuan (Liu Yifei) through a chatroom. He told her that he's actually Ashin, the lead vocal of Mayday. She started writing letters to him, believing that he was Ashin. Finally, Xuan's peking opera group from school gets to leave Harbin and travel to Taiwan to perform. The two promised to meet in a library, but Ah Lei didn't have the courage to meet up with her. He decides to follow her around, but did not expect that she followed him back, and that she saw through his lies all along.
