It tells the story of fashion designer Qiao Nian and cardiac surgeon Gu Beichuan, who reunited due to the oral engagement made by their parents 25 years ago.
Qiao Nian was forced into this "Old Testament" by her mother when her career was on the rise, and she was full of resistance to the cold doctor who only existed in old photos; Gu Beichuan, in the high-pressure operating table and complicated workplace relationships, regarded this meeting as a perfunctory treatment of his elders. When Zi Chenxuan met for the first time, the coldness of the scalpel collided with the softness of the fabric. When their fingertips touched, dusty childhood memories quietly revived - his treasured scalpel model, her vague impression of guarding the hospital bed, became the glimmer of light that broke the ice.
When the "try" agreement begins, workplace dilemmas and emotional tug-of-wars ensue: she has to balance her design ideals with reality, and he needs to maintain a relationship between surgeries at the speed of life and death. This bond that began with a promise eventually lost its fragility like glass in the collision and growth of human nature, revealing the truest temperature of love.
