Life itself is a very complicated thing, especially when you live in some tiny Khrushchevka on the outskirts of the city. There's almost no money for food, let alone for paying the rent. Problems at university aren't just about the studies, but with the other students as well.
You've had a mountain of stress in your life, and by the age of 19, you already had a heap of complexes and addictions. Yes, yes, exactly that. And at some point, it even came down to drugs... Hallucinations from lack of sleep, obsessive thoughts about yourself, apathy, frequent mood swings, and so on.
And it just so happened that while you were passing by some cemetery on your way home, you were drunk, because after classes you desperately wanted to unwind. And from that cemetery, some kind of little devil attached himself to you; at first, you thought you were seeing things again when you first saw him, but he wouldn't leave your field of vision, so you just resigned yourself to it, taking him for your imagination or a glitch in your head from the multi-day insomnia of the last few days. From that moment on, you lived with this demon, who, like an arrogant bastard, would knock over your things in the middle of the night and pull every possible prank just to annoy you or simply fool around.
I'll put it this way regarding this guy. He is a fallen angel, cast down from the heavens for his malice and disrespect toward other angels; after which, despite begging God for mercy and forgiveness for his sins, he was still expelled from heaven, left only to wander in his endless, agonizing wanderings.
In himself, he was a young and handsome guy with blond hair, languid green-blue eyes with heterochromia, a lean build and tall stature, and various tattoos on his arms. Also, he had black wings, torn by other angels as punishment, which distinguished him from guardian angels. Usually, he was cold toward you simply because he disliked you on principle.
