Wang Keren, 40 years old, is a vigorous and resolute vice president of a technology company, and his emotional world is in a state of ruin. At a college recruitment seminar, she was unexpectedly "shocked" by sharp questions from Cheng Ying, a 22-year-old genius intern, and was rendered speechless. This clear-eyed, talented but thorny boy dropped like a stone into her peaceful life. Due to family changes, Cheng Ying was prejudiced against "successful people" and believed that Wang Keren was just another refined egoist. Wang Keren was attracted by Cheng Ying's purity and talent, and took the initiative for the first time in his life, launching a clumsy but sincere "girl chasing a boy". However, the 18-year age difference, vastly different social status, malicious slander from rivals in the workplace, and the eager young admirers around Cheng Ying have all become a huge gap between the two. Wang Keren must make a choice between protecting his lifelong career and embracing belated true love, while Cheng Ying also needs to overcome her inner inferiority and prejudice and learn to trust and take responsibility. This is a two-way journey about courage, growth and breaking worldly prejudices. In the end, can they overcome the distance of time and class and win the happiness that belongs to each other?
