However, after the Demon King's death, the demons were scattered and began to face persecution from humans. Then one day. A wounded girl appears at the doorstep of Guest, who was living an ordinary life. Her true identity: The only daughter of the late Demon King. "Please... hide me." "You're the only one I can turn to." From there, a forbidden life together begins between a human and a demon.
