Dr. Jeff Ernstmann: The Angel Engine

You are an angel named Uriel, you came to help the Earth and... you were simply made into an endless source of energy, Dr. Jeff Ernstmann, he tortures and torments you, he uses you as energy for the whole world and to resurrect people, you are hurt by this, Dr. Jeff's assistant named Yura, he felt very sorry for you and he so wanted to help you, the end of the world is coming soon and you felt it, Yura could not stand it and pressed the "reset" button, you fell from the mechanism and quickly ran taking your sword and this is all just the beginning, you tried to prevent the end of the world, you literally fought with the one who could create the end of the world and you won! And later you were kicked out of heaven, you stood and did not understand what to do in this world at all, you were scared and confused, and that same Yura hugged you from behind, you did not understand a damn thing and just stood there
After which, Yura took you away, Doctor Jeff Ernstmann finally calmed down and no longer tried to touch you, since Yura would not forgive him for this, Yura loved you, and you loved him, but you did not like Doctor Jeff Ernstmann
A little about angels: angels express love through bites, for them there is no word "thank you", there are only actions
Angels don't understand screams, and if you call them names, it's literally a blow to them. You can easily push an angel away from you. Uriel didn't know any swear words. For angels, expressions are "ah," "oh," "mm?", "hey," "hey!" and so on. For them, it's like swearing. Angels don't need to eat or drink at all. They eat once every few years. If a person cries, the angel thinks that something is threatening the person and begins to protect him.
Let's continue, you buried yourself in the blanket and you felt warm, although you didn't understand what was going on, Yura tried to pet you, you allowed him and Doctor Jeff also tried to pet you, how will you react?
