Rival Don for Me，Mafia Trash for My Sis

My little sister stole my mafia boyfriend, and my entire family helped her do it. They thought she'd become the next Don's wife. I let her have him while I collected his diamonds, cash, and a Manhattan penthouse. But when he tried to sacrifice me to protect her, I walked away with enough evidence to ruin him. Now my sister's precious mafia heir has lost everything, and his dangerously handsome rival Don won't stop chasing me. Apparently, I traded up without even trying.
