Su Wan, an ordinary migrant worker, repeatedly encountered obstacles in the workplace. On a rainy night, she was trapped in front of the company with an important contract. She was accidentally rescued by Lu Chengze, the group's technical director, holding an umbrella. This young, promising but lonely director was moved by Su Wan's sincerity and kindness, and began to pay close attention silently. The two frequently intersect in the workplace and in life. Although they face the obstacles of identity gaps, workplace rules and family relationships, they always support each other and resolve problems with love. They not only depict the various situations in the workplace, but also depict pure and passionate love.
