There's nothing wrong with love.

Wang Yulan was widowed at a young age and lived a hard life with her two sons. With her tenacious perseverance, more than a decade later, she established her business empire. Her eldest son Zhang Binghua was considerate, obedient, and sensible since childhood, but for some unknown reason, he could never get his mother's smile or embrace. This made him puzzled - why could his younger brother Zhang Bingguo receive so much love from their mother? Thus, getting maternal love became the greatest desire of Zhang Binghua's life. The brothers Zhang Binghua and Zhang Bingguo had deep affection for each other. One day, Zhang Bingguo saved his brother's life by risking his own, which resulted in being severely injured in a car accident and becoming permanently disabled, relying on a wheelchair for mobility. From then on, besides yearning for maternal love, Zhang Binghua also carried an unshakable sense of guilt towards his younger brother. Zhang Bingguo fell in love with Nurse Shao Ting during a chance encounter. However, due to his disability and self-abasement, he didn't dare to pursue her. Wang Yulan, out of maternal love, went through great efforts to find a perfect girl for her youngest son. By coincidence, she met Shao Ting and decided to arrange the marriage between Zhang Bingguo and Shao Ting. Shao Ting was an adopted daughter, kind and filial. Her sister Shao Xiao, who was in university, suffered from severe mental trauma after being raped. Shao Ting proposed a surprising condition: if the disabled Zhang Bingguo wanted to marry her, his elder brother Zhang Binghua must marry her sick sister Shao Xiao. In order to please his mother and brother, Zhang Binghua accepted this condition, painfully breaking up with his long-term girlfriend Gao Dandan and marrying Shao Xiao. This decision was bound to bring greater storms to the Zhang family. One day, the truth about Zhang Binghua's origin was finally revealed. It turned out that he and Zhang Bingguo were half-brothers sharing the same mother but different fathers. His biological father was none other than Gao Dandan's adoptive father, Gao Xudong. Years ago, Wang Yulan was misled by her friend He Zhimei and mistakenly thought that Gao Xudong had abandoned her after seducing her, forcing her to marry Zhang Bingguo's father, Zhang Kai while pregnant. Ever since, whenever she saw her eldest son Zhang Binghua, it would remind her of the painful past, so she had been reluctant to show him any smiles over the years. Zhang Binghua's sacrifices for her and Zhang Bingguo moved Wang Yulan. Just as she was wholeheartedly trying to rebuild the mother-son relationship with Zhang Binghua, a fire destroyed her lifelong endeavors and also her yet-to-be-paid maternal love.
