He has a pair of eyes that can see through the world. He is the demon king who has ruled the demon clan, the ghost realm, the demon world, and the spirit world for more than a thousand years. He is rich and can eat both black and white, but he is always the same. He is not a pure-hearted person, but he only wants to keep that one girl.
She was the one who survived the disaster, and was his sister-in-law in name. In fact, the two of them were lovers. This relationship started that day and lasted for five years. She also had a secret. What did she want to do by staying with him?
He has been an orphan since he was a child. He has a powerful adoptive father and a woman who is like a sister and a mother. They say they will protect him throughout his life. She will accompany him to grow up and he will accompany her until he grows old. Is this a conspiracy? Or a surprise?
Intention: A happy ending, but not the final ending
