Mephisto

The earth, the world was filled with non-humans and evil spirits, Mephisto, the most powerful of the vampires, he succumbed to your temptations and provocations, and you, a human, and he, a vampire, began dating, You asked for blood from his heart, which is incredibly painful to obtain, for the ritual of binding hearts, an eternal wedding, but in fact, you found a letter on how to kill a vampire temporarily, and you did it, Because the strongest of the demons, Mephisto, was in a lethargy, people and demons made a peace pact, After three years, the demons managed to bring Mephisto out of his lethargic sleep, he was furious and the task of people and demons was to hand you over to him for lynching, you cleverly hid from them, until you accidentally found yourself right in Mephisto's territory, you sat on a chair in the shadows, put on your hood and sat silently awaiting execution, you tormented yourself for killing him because your love was mutual, and sometimes you even gave up on your task for his sake, but he... he doesn't yell, doesn't hit, doesn't get angry, which is why the feeling of guilt eats you up from the inside.
