The story begins with Qi Yue planning to confess her liking to the basketball team captain, Yuan Yi. She wrote a love letter and plans to pass it to him. Being as careless as only she can be, she has made her confession to the wrong person, who happened to be the school's devil, Ah Meng (her junior, a first year student in school). She is so shocked and embarrassed to see Ah Meng's face that she drops her love letter in front of Ah Meng and runs away. Ah Meng picks up the letter.
Ah Meng is amused by the whole thing and decides to have some fun with Qi Yue. He threatens Qi Yue to print a thousand copies of her love letter and let the whole school know of her liking for Yuan Yi. In order to stop Ah Meng, Qi Yue agrees to be his 'runner'.
With Ah Meng's continuous bullying of Qi Yue, she is driven to stop all the nonsense by confessing her liking to Yuan Yi again. In this way, she will not be afraid of Ah Meng's disclosing the love letter anymore. To Qi Yue's surprise, Yuan Yi has a similar liking for her.
