Bo Yi's mother came from a third-rate noble family, and she never would have joined the Bu Family if she hadn't successfully hooked up with Mr. Bu.
The maternal family of Bo Xiao, the Song Family, was indeed a first-rate noble family and Mrs. Song's death had left behind a considerable fortune.
The Song Family helped Bo Xiao acquire that fortune.
Because of this, even though they both came from the Bu Family and shared the same father, Bo Yi's situation was much more strapped than Bo Xiao's.
Mr. Bu did indeed favor the mother and daughter of Bo Yi, but he wasn't the only son in the Bu Family; the direct lineage was prosperous with many branches, so the resources and pocket money allotted each month were limited.
Of course, compared to other noble offspring, Bo Yi was already among those at the forefront.
But compared to Bo Xiao, the difference was huge.
This was also one reason why Bo Yi particularly despised her sister Bo Xiao.
