Yang Xiaorou was originally born in an unknown mountain village in Sichuan. One day many years later, she was taken to live in a big city by her biological father whom she had never met.
Yang Mingxu, who went with her back then, vowed to love this suffering sister at the first sight when he saw her, but later fell in love with her. However, things are unpredictable, and this will eventually be a fruitless love affair.
Qi Ming, the second son of the Qi family, has been in the same class as Xiaorou since the third grade of elementary school. On the first day of school, he ridiculed Xiaorou for being a "bumpkin". Afterwards, he often came up with some random ideas to bully her. The feud between the two lasted until they entered college. One day, Qi Ming suddenly found that the bumpkin in front of him was extremely "delicious", so he joined in the fight with Yang Mingxu's former love rival.
