My Mafia Don Hates Me by Day, Loves Me by Night

I was forced to marry a Mafia Don under my twin sister's name. By day, I'm Stella—his exhausted assistant, the woman he publicly humiliates without mercy. By night, I become his secret wife, the only one who can make the cold, ruthless Don turn desperate. He thinks I'm Chloe's innocent twin. He has no idea the assistant he can't stand and the wife he kisses every night are the same person. Then Chloe comes back—and the truth begins to surface.
