Contract with the Abyss The Demon CEO's Substitute Bride

Short-form drama fans, this one goes down easy and hits hard. On the surface this is a Romance serial, but underneath it is a story about two people orbiting one inevitable collision — and "Contract with the Abyss The Demon CEO's Substitute Bride" plays both layers for all they are worth.

Intern Serena signs a substitute-bride contract to cover her adoptive mother's surgery fees, pressured by her vicious sister, and marries the CEO rumored to be a bloodthirsty monster. The rumor undersells it: Lucian is the pureblood demon lord who actually rules the underworld — and his abyss curse responds to the rare blood Serena does not know she carries. Gothic office romance with a genuinely nasty streak of danger.

Tropes on the menu: forced love, stand-in. Episodes are bite-sized, the cliffhangers are ruthless, and the payoff lands faster than most full-length shows manage in a season.
