In the late 1980s, after years of appeals from veterans in Taiwan, the two sides of the strait finally opened up contact. Kang Jun, who had left home as a child, returned to his hometown on the mainland with his wife, Liu Zhizhi, to visit his elderly parents. Only when he saw his mother did he learn that his father had died after he was taken away. A childhood friend from his village, A Zheng, had saved his mother and spent the following decades treating her as his own mother, caring for her until the end of her life. Grateful for A Zheng's kindness, Kang Jun brought his twelve-year-old daughter, Kang Meiying, back with him to Taiwan.
Kang Meiying went to Taiwan with her uncle and aunt, and her sincerity touched Kang Jiaming, whose disability had left him feeling inferior. After her family died, she was forced to marry her own brother, Kang Jiaming. By chance, she met the siblings Xiaoshan and Xiaoqing. With the help of her senior Luo Guanliang, his siblings, and other classmates, she struggled through life. Later, she met Junjun, who had been in a car accident, and Lele, an adopted child. Through her tangled relationship with Luo Guanliang and her life with the four children, she formed bonds that would never be broken.
