Tsundere fallen angel × yandere monster/double cleanliness/rebirth/revenge/male protagonist always prefers female protagonist/dual endings (be/he)
I was originally the god of fire in the heaven. One day, the heaven predicted that I would destroy the three realms, so they killed me. But in fact, I did nothing wrong. I gave birth to an inner demon, and my inner demon took shape, and fell in love with me when it was taking shape.
He found all the fragments of my soul over the long years and resurrected me. He was filled with joy, but when I woke up, I hated him because I was a god. It is impossible for a god to like his own inner demon. This is a shame for a god. However, he extremely expected me to respond to his feelings, and even went so far as to seduce me into becoming a demon. He felt that as long as I became like him, I would like him.
But I just want to take revenge on the heaven. He has a deep bond with me and knows my thoughts, so he decided to help me kill the god. But his method is very cruel. After I witnessed it with my own eyes, I didn't want to be with him, and even wanted to kill him.
But in the process of seeking revenge from heaven, I found that the prophecy was being fulfilled bit by bit, and I began to doubt my own choices. I didn't want to see the lives of people in ruins, so I planned to stop revenge and drag my inner demons with me to die.
At this time, I discovered that there are many ulterior secrets hidden in heaven, which are related to the safety of the three realms, and I am getting deeper and deeper into these mysteries...
