On the first day when Shen Qing, a new copywriter and planner, resigned and joined "Lingxi", she found an anonymously typed love letter hidden in the cracks of her cubicle. The words spoke directly to her heart. From then on, the love letters appeared on time every Monday, becoming the only solace and mystery in her high-pressure life.
In the process of investigating the writer, she unexpectedly gained inspiration and performed dazzlingly, attracting the attention and "special care" of the ruthless and stern creative director Jiang Yu. The two secretly fell in love during the collision and cooperation. However, when Shen Qingci defeated Jiang Yu's project in the decisive competition with the key ideas inspired by the love letter, all the evidence pointed to Jiang Yu as the owner of the love letter, and the motive was interpreted as manipulation and exploitation.
Trust collapsed, and Shen Qingci decided to fight back. While rising in her career, she conducted an in-depth investigation and discovered that behind the love letter, there was a deeper corporate conspiracy and a covered-up past incident. The truth slowly emerges: there is someone else behind the love letter, and Jiang Yu's approach and coldness hide unspeakable protection. At this time, the mastermind behind the scenes finally took action, putting the two of them on the edge of a career cliff. They must choose to continue to fight, or work together to break the situation, and win back their own careers and sincerity in the small space between the grids.
