Luo Yi lives quietly in the old streets of Su City, running the Half-Cup Tea House. When a redevelopment project for the historic district begins, she unexpectedly crosses paths with Song Yu, president of Song Group. At first, Song Yu relentlessly pressures her in an attempt to acquire the land, only to be repeatedly thwarted by Luo Yi, a woman with exceptionally firm boundaries. He pretends to become her tea apprentice to get closer to her, intending to win her over for his own gain. Unexpectedly, their daily interactions make him fall deeply in love. As they test each other and alternately advance and retreat, feelings grow between them, but they face rival schemes, revelations about their backgrounds, and one crisis after another. Breaking free from manipulation and prejudice, they shed their sharp edges and reject a relationship built on dependence, ultimately choosing to become partners who stand side by side, both in life and in love.
