Love within the system does not have any dramatic scenes, but it hides the most practical support for each other - he is the prison guard/Nanzhou firefighter Jiang Chi within the high wall, guarding the peace with iron discipline; she is Su Qinghe, the director of internal medicine at a tertiary hospital, saving lives and healing the wounded on the line between life and death, and resisting the wind and rain on the medical road with gentleness and tenacity.
An emergency rescue in a prison brought two people who were fighting on different "battlefields" together. He was used to seeing struggles within high walls, but he was moved by her calmness and courage in the face of crisis; she had seen all the joys and sorrows in the ward, but was attracted by his delicate and considerate nature under the tenderness of his tough man. The constraints of the rules within the system, the shift system of getting together less and being more separated, and the misunderstandings and worries caused by the special nature of the profession have become obstacles on their way to falling in love: his loss of contact during the night shift kept her awake all night, and her grievances when dealing with medical troubles made him heartbroken. The concerns of both families about "high-risk occupations" made the relationship even more difficult. From cautious exploration to firm hand-in-hand support, they shine in their respective positions and heal and grow in each other's company. He learned to leave a softness outside of the iron rule, and she knew how to show a hint of vulnerability behind her strength. When the responsibility of a prison guard meets the mission of a doctor, when fierce protection blends with gentle healing, they use trust to break the barrier of distance, use understanding to resolve real problems, and finally enter the marriage hall with the blessings of relatives and friends.
