My Sister's Boyfriend is My Fiancé

After the parents of my cousin, Hollie Cox, died, she finished college with my help.

To repay me, she married my fiancé, George Marshall, who was born with a silver spoon in his mouth. Per her, wealthy men would treat women as playthings, and she would sacrifice herself for me.

She sold George's idle luxury car, saying it was a birthday gift for me.

She broke the spending limit of George's supplementary card, saying that she was repaying my loan to the loan sharks.

She, who was pregnant, suffered serious bleeding while fooling around with George's uncle, Mark Marshall.
