Workplace elite You Shuang lives alone, enduring year-round high-pressure work and her supervisor's harassment. Chi Yu, the dessert shop owner next door, appears sunny and gentle, but is actually paranoid and stubborn. He uses desserts to create deliberate chance encounters, figures out You Shuang's physical weaknesses like hypoglycemia, and continuously crosses boundaries to get closer through feeding and scent penetration. You Shuang builds her mental defenses with reason, resisting this aggressive show of goodwill, but her instincts are quietly shaken, and the two fall into a dangerous and ambiguous tug-of-war game.
