Shen Yi lives in a poor single-parent family, and her father tries his best to find various jobs to support her education.
In his senior year, Shen Yi worked as a full-time tutor for Li Zan, a senior in high school, and got to know Li Zan's deskmate, Shi Yu, a problem student in everyone's eyes.
Master Shi's thousand-year-old iceberg face was split open easily by Shen Yi, an inconspicuous elder sister!
Kim Sam Soon? Cinderella? All the names expressed the strong dissatisfaction of the whole school against this "Obasan"...
Family background, age issues, are these the only things that stand between the two? The answer is of course "NO". The Shi family's opposition is necessary; the pointing fingers of people around him are necessary.
So, Shen Yi chose to be an ostrich, just for so many years.
Many years later, Shi Yu came back from abroad and found that Shen Yi had married someone else.
However, he inadvertently discovered that Shen Yi and his current husband Qiu Ruogu were only a couple in name.
At this time, "stepping in" was his style as Young Master Shi. Well, Shi Yu once again chose to dedicate his best years to his eldest sister back then and now his aunt!
But he never expected that the development of things would be far beyond his control!
