Wu Zheng, a civil aviation captain, has an enviable career and appearance. He is skilled in flying and bears the responsibility of countless passengers. In life, he is uninhibited by nature and loves freedom. He is free to do whatever he wants, regardless of other people's opinions. In his own world, he is a thorough old boy. Until one day, a 16-year-old son fell from the sky, followed by a righteous female teacher Lin Xiaoou. The arrival of the two completely subverted Wu Zheng's existing life. Lin Xiaoou, a carefree optimist, is a little bit fashionable and a little bit reckless in justice. She is the students' kind sister, a hearty friend and a good teacher without airs. When she learned that her favorite student Xiao Han suddenly suffered a family change and became a homeless orphan, she tried her best to communicate with the child's biological father. When she met the child's biological father, she found that he was her nightmare when she traveled abroad not long ago-Wu Zheng, who was against her everywhere and extremely unreliable.
