A corner bookstore in a small town may hold clues to a woman who went missing after going to Bi Jia Mountain alone years ago. Xiang Shu Lei (Lee Wei) was dating Du Ke Jie (Tracy Chou) but had an affair with her friend, Dong Xin Ni (Chloe Wang). One day, Ke Jie goes to Bi Jia Mountain alone and never returns. Riddled with guilt, Shu Lei and Xin Ni break off ties with each other. Ke Jie’s younger sister, Ke Xing (Nikki Hsieh), and her parents are heartbroken over her disappearance but gradually come to terms with the fact that they will never see her again. They begin to pack up Ke Jie’s belongings, not knowing that Shu Lei has secretly taken all of Ke Jie’s beloved books. Then tragedy strikes again when Shu Lei gets into a car accident and loses his memory. He then moves to the small town of Yi Lan and opens a bookstore with Ke Jie’s books. When Ke Xing finds the store and discovers Shu Lei’s amnesia, she and her boyfriend, Li Ze Xuan (Alien Huang), try to jog Shu Lei’s memory for their own personal gain. But will Ke Xing’s feelings get in the way of their plan?
