Not the Heroine of This Love Story

After waking inside the beloved romantic fantasy webnovel 'The Duke's Light,' Su-Jin uses what she knows as a reader to dodge her scripted death and keeps a low profile as a cafe maid near the heroine's glamorous romance. But the scenes she assumed were harmless courtship begin showing traces of blood, and the seemingly angelic heroine finally reveals the truth: the romance is nothing but a disguise worn by something that hunts anyone who strays from the script.
