Su Yining is a new product manager at "Yunqi Technology". On her first day of employment, she discovered that her immediate boss was her first love of three years in college - Technical Director Lu Chenzhou. Back then, the two broke up because Su Yining wanted to stay in the local area to start a business, and Lu Chenzhou wanted to study abroad. Now they reunite. One is a newcomer who needs to prove his ability, and the other is a demanding boss. The intersection of work makes the past feelings continue to surge.
Lu Chenzhou was cold on the surface, but secretly helped Su Yining when she encountered a project crisis; Su Yining deliberately kept a distance, but was once again moved by his professionalism and gentleness during the cooperation. During a cross-department project competition, the two were forced to form a team. Faced with difficulties from their opponents and rumors within the company, the misunderstandings about their past breakups were gradually resolved (for example, Lu Chenzhou went abroad to help Su Yining pay off her entrepreneurial debt). At the project success celebration banquet, Lu Chenzhou confessed his feelings in public, and Su Yining could no longer hide her suppressed emotions. The two finally faced their hearts and re-wrote the story of their first love amidst the fireworks of the urban workplace.
