From then on, she wandered from place to place with the young Shen Zhixu. Six years later, Su Wanyin is suddenly involved in a car accident. Her six-year-old son, Shen Zhixu, desperately seeks help to save her, standing guard outside the ICU with his small but determined shoulders. Moved by the child's devotion to his mother, Brother Qin, Hou San, and Director Wang all lend a helping hand. Shen Zhenglan, the father who had been separated from them for years, also arrives after following a keepsake. As Su Wanyin awakens, the truth hidden for six years gradually comes to light. Facing those who try to obstruct them, the family protects one another and bravely perseveres, ultimately bringing the truth into the open and reclaiming the long-delayed joy of reunion and a warm new life.
