A stranger texts at midnight about tasting the world differently. A wrong turn down a black forest road later puts him in the headlights, bloodied and barely able to say his own name. He is a ghoul who guards that road, and a witch confirms what he fears: he is falling through seven cycles of sin one at a time, and when the last one closes his humanity is gone. Forty-five chapters of a courtship run against that clock, ending in a forest wedding and a blood vow.
