Too Late, King: I'm the Goddess

Avril, drained after vanquishing the Demon God, fell to the mortal realm. King Alistair saved her, and she forsook godhood to wed him—only to be framed for treason by his true love Seraphina. Luckily, she was saved time and again by Hades, the Lord of the Underworld, her admirer for three millennia. Regaining power, she found Seraphina the real traitor. And when the Demon God broke free again, Avril and Hades killed both him and Seraphina. After that, Avril moved on, and wedded Hades in a grand ceremony.
