Lin Yan is a decisive project manager, and Shen Yu is an outstanding backbone in the team. Together, they tackle major projects, supporting each other through countless late-night overtime sessions to resolve endless challenges. Professionally, they are a tacitly cooperative superior and subordinate; personally, amidst day-by-day joint struggles, restrained admiration and affection blossom. As the project reaches its finale and currents surge beneath the celebration banquet, they choose to keep these feelings hidden in their hearts, maintaining professional propriety in the workplace, and searching for the answer that belongs to both of them between ideals and romance.
