Cheng Zinuo's house and Ge Yifeng's house were next to each other. However, Cheng Zinuo had never seen Ge Yifeng at that time.

Ge Yifeng's parents are divorced, and Ge Yifeng lives with his father.

His mother had later moved to another country to settle down, and his father had married a woman who was more than ten years younger than him.

Since then, Ge Yifeng had a stepmother.

Every time Ge Yifeng's father was out on a business trip, his stepmother would make things difficult for Ge Yifeng — either forbidding the butler to cook for Ge Yifeng or picking on Ge Yifeng's fault, which would pinch Ge Yifeng until his body turned black and blue. The reason why she pinched Ge Yifeng's body was because no one could see those wounds after Ge Yifeng put on his clothes.
