Game of Blood

If you binge vertical dramas on your phone, queue this up tonight. On the surface this is a Romance serial, but underneath it is a story about payback served cold — and "Game of Blood" plays both layers for all they are worth.

Irma is one swing from the executioner's block when Crown Prince Lukian — dying of a curse that only black blood can soothe — buys her life to use her as his cure. His touch heals without pain, a resonance nobody can explain, and that mystery is the romance. The show then detonates her trust twice: he let her best friend die feeding the same ritual, and his icy fiancée Rina has spent decades killing black-blooded women, including Irma's mother.

Tropes on the menu: strong female lead, revenge. Watch it in one sitting or savor it nightly; either way, the hooks do their job.
