For three hundred years the Covenant hunted witches to extinction — and Seo-yeon, a barista who heals paper cuts when no one is looking, has no idea she is the last one left. When her magic flares in public and saves a dying stranger, every hunter, collector, and cursed prince on the peninsula converges on her café. The stranger she saved turns out to be the Covenant’s heir, sworn to kill her kind and inconveniently in her debt. Twenty episodes of forbidden magic, ancient grudges, and a love story that could either end the war — or end the world.
