God, Being an Assistant Is Deadly

DramaBox synopsis

Damien, a mafia heir raised in hiding, saved Sebastian Kingsley as a child and became his secretary and bedmate. Over a decade, Damien fell in love—but Sebastian treated him as a tool. Humiliated before Sebastian's engagement, Damien left when the contract expired and reclaimed his own power. When they met again, their positions had reversed—Damien now held all the cards.
