Through their collaboration and as the day goes by,their friendship evolves and they learn more things about true love.
The film opens in the present day, where Lin Cheng-hsin (Joe Chen) is an ordinary office worker who leads a stressful life.
Her name, "Cheng-hsin", literally means "sincere of heart", reflecting her hardworking nature which often gets her ridiculed by her younger subordinates.
Dejected, she listens to a cassette recording of an old Andy Lau song. This brings her back to her high school days, when she was an ordinary high school girl, who idolised Lau and lived a simple, carefree life.
She had a crush on Ouyang Fei-Fan, (Dino Lee), the school's most popular male student, and had two good girl friends.
One day, 17 year old Lin (Vivian Sung) receives a chain letter, warning her of impending doom if she does not pass the message on.
Naively, she passes it on to Hsu Tai-yu (Darren Wang), the school's notorious gangster boss, her math teacher and Tao Min-min (Dewi Chien), the school's most popular girl. While Tai-yu reads the letter, he gets hit by a car.
After weeding out the letter's sender, the angry Tai-yu makes Cheng-hsin his 'friend' and forces her to run errands for him in exchange for leaving Ouyang alone, thus making her his errand-girl.
By chance, Cheng-hsin accidentally overhears a conversation between Min-min and Ouyang and discovers that they are in a secret relationship.
Dejected, she creates an alliance with Tai-yu, who likes Tao Min-min, to break the couple up. Throughout the course of events, Cheng-hsin and Tai-yu begin to understand each other better, and their friendship evolves as they began to learn a thing or two about true love.
Eventually, they develop feelings for each other.
Tai-yu later discovers that he has a blood clot in his brain, caused by the car accident and further exacerbated by his frequent brawling and falls. His parents decide to send him overseas, leaving Cheng-hsin with no way to contact him in an era without social media. 18 years later, Cheng-hsin leaves her unhappy job and relationship upon having rediscovered herself. She is still unable to book a ticket to an Andy Lau concert that is set to take place in Taipei, but fate intervenes and allows Lau to act as the means by which Lin Cheng-hsin and Hsu Tai-yu (Jerry Yan) are reunited as adults.
