Accidentally Married to the Demon Lord

Lilith, a mocked‑for‑failure magic apprentice, sneaks into forbidden archives to pass her exam and accidentally summons Demon Lord Azriel. He claims her as his contracted wife, turning her into the famed Demon Lord’s Consort. They join forces to seal the Abyssal Fissure. Deprived of demonic power, Azriel becomes human, and the pair run a potion shop for a sweet peaceful life.
