Shen Zhixia, an aloof female lawyer, was traumatized by witnessing her mother's suicide in her childhood. She closed her heart and became an "iron judge in divorce cases." However, after a court hearing, she met Wen Shiyan, a sunshine pediatrician. He melted her defenses with his pure warmth, and the two gradually got closer, but they were framed by the hypocritical best friend Lin Wanzhi, which led to the misunderstanding of "Shen Zhixia taking advantage of Wen Shiyan". Shen Zhixia fell into a career low due to evidence tampering, and Wen Shiyan was framed and lost his medical qualifications, and the two were forced to separate. They reunited many years later. Shen Zhixia became a public interest lawyer, and Wen Shiyan switched to child psychotherapy. The two reunited in a case of helping abused children. Together they uncovered Lin Wanzhi's hypocritical mask, but discovered that there was a deeper trauma hidden behind the misunderstanding - Shen Zhixia's father actually had an interest in Lin Wanzhi. In the end, can the two overcome the frost of time and let the sunshine shine into each other's coolness?
