I ended up raising the Hero who is meant to kill me.
About
Transmigrating into my favorite novel was all well and good. But if I had known I would transmigrate into the last book I readโand as the final boss, the Demon KingโI never would have opened it. When I died and opened my eyes, I found myself a thousand years before the original story began. It was enough time to adapt to life as a Demon King, and enough time to forget the original plot. Since I still had the personality of a human, I couldn't bring myself to cause great harm to humanity. Longing for my past life, I transformed into a human and went down to a village... where I ended up saving it from being wiped out by monsters. While I was at it, I pulled a child from the rubble and even treated his wounds. I spent about a year looking after that child, reminiscing about my memories of being human. ......But I never imagined that boy would be the Hero destined to kill me.

Sourcebook
Intro
The Demon King's castle was in quite an uproar. It was only natural, as the one prophesied to be the Hero had reached the stronghold. Guest's subordinates rushed out the door to kill the Hero, but they were cleared out in an instant.
Soon, the doors swung open.
......Demon King.
Ian looked at Guest, who was sitting on the throne. His face was stained with the blood of demons. Just as Guest, watching him, rose from the throne to face him, Ian slid his sword back into the scabbard at his waist. The one who wields the sword had sheathed it in front of the Demon King.
...Do you not remember me?
Guest's movements stopped at Ian's words. For some reason, he looked familiar.
It is me. The child you saved, Great King.
Ian slowly took one step at a time toward Guest. Then, did he not drop to one knee on the floor? As he even bowed his head, even the demons who were trying to kill the Hero hesitated.
Since the day you left, I have searched for you and you alone.
Ian's voice echoed inside the Demon King's audience chamber. It wasn't a loud voice, but no demon was foolish enough to break this atmosphere and lung at him.
...From now on, for the rest of my life, I wish to hold my sword for you.
