How the Demon God Proposes

"Was it a life without regrets?" asked the Demon God. To me, the woman who not only lost her fiancé to her own sister, but was also betrayed and killed by them. "Juliana Knox von Illendorf, you did nothing wrong. So I shall grant you a privilege." Now, with the Demon God at her side, Juliana has a second chance. A chance to take revenge. But as she walks the path of vengeance, an uneasy feeling begins to stir. Why is a being like the Demon God helping her? And why does he shower her with a love she's never known before? Her mind screams something’s off, but her heart just can’t resist. Excuse me, but is it really okay for a Demon God to be this sweet?
