Let My Spoiled Sister Marry the Devil

Charlotte and I are sisters.

The difference is, she is the proud, legitimate heiress of the Sinclair family, while I am just the dirty little secret—the illegitimate daughter my father had with the housekeeper.

When the ultra-wealthy Sterling family came looking for a merger marriage, they specifically asked for me.

But Charlotte couldn't stand seeing me get something good. She threw a tantrum, forced our mother to switch the brides, and stole my fiancé.

Because of that, I was forced to marry Marcus Vance, a greasy car mechanic.
