Wei Chen, a low-level migrant worker with a rare surname and an ordinary family background, married into the Su family in order to raise money for his seriously ill mother, and became a "soft rice" son-in-law in the eyes of everyone. He was taciturn, leaving early in the morning and returning home late every day, working on the subway, and doing odd jobs. He endured the contempt of others, but gave all his tenderness to his wife Su Wanqing. Su Wanqing is the youngest daughter of the Su family. She is gentle and kind. She never dislikes his origin and silently accompanies him through the most difficult days. Even if her family complains about "marrying the wrong person", she always stands firmly by his side.
In an accident, Wei Chen won a billion-dollar lottery and transformed from a migrant worker with limited food to a wealthy man overnight. But he did not show off, nor did he abandon Su Wanqing. Instead, he just wanted to use all his wealth to make up for what he owed her before - he bought the entire counter for the jewelry she mentioned casually; he slept with her every night because she was afraid of the dark; and if others dared to look down on her, he would use his strength to protect her.
From a migrant worker squeezing the subway to a billionaire doting wife, Wei Chen's only obsession is to give Su Wanqing the best in the world. "Wan Qing, I didn't have the ability to let you live a good life before. In the future, as long as I am here, no one will dare to let you suffer a little injustice." This is a sweet love between a son-in-law and a son-in-law that begins with responsibility, sinks into tenderness, and finally becomes pampered. There is no bloody house fighting, only preference and warmth that go both ways.
