Business tycoon Rong Yanxiu was recuperating at the Zhou family's old house in Beijing three years ago. He fell in love at first sight with Wen Qingyao who came to pay New Year's greetings, and waited silently for her saying "I will fall in love after taking the postgraduate entrance examination." Three years later, he took the anniversary of the University of Hong Kong as an opportunity to recruit Wen Qingyao, a first-year graduate student, to join Rongshi as an intern. With zero love experience, he was clumsy at first, but gifts of jewelry and direct confessions drove the sober and rational girl further and further away. He put away his tricks, silently guarded her, and helped her grow from a novice in the workplace to a business partner. The two transcended class differences, worked together to overcome family resistance, and finally realized that love is mutual achievement. Many years later, the family of four is living peacefully, proving that the longest love confession is growing up side by side.
