Scandalous Maiden (Secret Lady demon)

“A well-known Holy hero was rewarded to be reborn after she killed her husband, who is known as Demon Contractor. Her husband became the villain of their kingdom. She is really in love with him. She had promised to stay with him in sickness and in health but it turns out, it was just her lies. She broke her promise when she couldn't regain her husband. When she was reborn, she was chosen to be one of the maidens that will be chosen for the king's royal consort. Their world is in Apocalypse. In order, to survive, the Gods need his/her people to give them rites. If those maidens are never chosen to be the bride to the Crown Prince, then they will die as a sacrificial tool for the rites. But she never dreams to continue her life again with such beliefs. She already met the True God. Those false Gods were only playing them. Therefore, she hid her slayer identity to kill the faith of those devotees. But a goddess caught her misbehaving, so the goddess reincarnated her husband into someone she never expect to be.”
