Reborn: The Demonic Palace Master

In my past life, I gave my heart to a scumbag. In this life, I'll make sure to keep it under lock and key. After being reborn, the palace master's ideal life is to let evil triumph over good, make those self-righteous members of the righteous sect grovel at his feet and call him Daddy, and keep all that romance nonsense out of the way. In reality, he went out without checking the almanac and ran into that damned man again. He thought he would be entangled with him once more in this life, but suddenly another, even more powerful demon appeared. That demon seems to know everything about his past and present lives. What secrets is he hiding? Theme:
