I Dumped My First Love to Marry a Rich Heiress, Then Found Out She Was Buried in Debt

My brother cheated on his wife.

When I found out, I didn't tell my sister-in-law.

Instead, I blackmailed my brother into buying me three handbags.

Only later did I suddenly remember that the woman he'd cheated with was his first love.

If he hadn't been forced to marry that heiress, the two of them should have been together.
