My Diablous King (Editing.)

Diablous is a cold hearted mafia king who's also a single father. He had a bad experience with an Ex lover which made his trust in women fall, that is untill the babysitter walks into his life.
Will she be able to understand their line of work? And there way of life? Or will it be to much for her?
She comes from a life where she only has her two siblings to lean on, perhaps working for the King's will reveal secrets and a whole new identity.
