The Su and Xia families in the capital city, one is a scholar and the other is a powerful businessman. Their houses are adjacent to each other and they have a deep friendship.
Su Yu'an, the son of the Su family, has been a famous child prodigy in Beijing since he was a child. He also has a clear face, picturesque eyebrows and gentle temperament. Xia Jingyao, the youngest daughter of the Xia family, is a pretty girl, but she has a bit of an unconventional temperament. She climbs trees to catch birds, goes down rivers to catch fish, and does naughty and trouble-making things all the time.
When he was young, Xia Jingyao climbed the wall to pick apricot flowers in the neighboring yard. When his foot slipped, he screamed, but Su Yu An'an was always there to catch her. His fingertips were stained with mud from her, and he was helpless and doting: "Next time you are so reckless, I will tell Aunt Xia." She got into trouble and was punished by her husband by copying books, so he silently helped her straighten out her crooked handwriting. She fell into the lotus pond out of fun, and he was the first to jump in and pick her up. He was wet and cold, and he covered her up by saying that he had made a mistake.
The Su family's parents saw this and just smiled and shook their heads; while the Xia family's parents were helpless, they were also very reassured by Yu'an's stability and reliability. The eldest sister Su often teases her younger brother: "Our thoughts on Yu An are all about the little troublemaker next door." The eldest brother Xia, on the other hand, whenever Jing Yao causes trouble, he first goes to Su Yu'an to "question the blame", but in the end the three of them always work together to figure out how to fix the mess.
As time goes by, Jing Yao becomes more and more beautiful, but she is still the little girl who loves to cause trouble; Su Yu'an becomes more handsome and tall, but the preference in his eyes only increases.
