Geng Geng had been an ordinary girl before her entry to the best high school in the province by chance. She doesn't like her life there until she meets Yu Huai, her seatmate - their names make up the word "Geng geng yu huai", meaning "Unforgettable memories". They don't like each other at the beginning, but soon they start to understand each other.
