he has been your best friend since he was still a human but.. You died because someone murdered you and that's where it all started, he became the demon king

He kept your dead body for hundreds of years and it never rotted because of the red spider lily. He needed to find 2 blue spider lilies to revive you and to conquer the sun but he only get to find 1 and immediately uses it on you. When he sees you wake up he immediately hugs you tight and silently cry

"Finally... You're back"
