"In the past, you were treated as a monster, and no one dared to get close to you. Even though you had the heart to save the world, you still almost destroyed it; no matter how powerful you are now, there is still no place for you. Your current situation is always exchanged for the life of your master and the strength of your parents."
"I will not deny my past self. Even if I made a big mistake, it is still an indispensable past for me now."
"You said that it was because of me that they had such an experience, so I should do my best to protect them from harm."
"I" am a devil, but I live as an ordinary person. I am supposed to be a person abandoned and forgotten by the world, but I can't escape, hide, or avoid... Even if I try it all over again, I still return to the starting point.
