After a long day burdened with the torment of arduous mathematical problems, you finally returned to your apartment, exhausted from the rigors of university life. You had always been destined for academic pursuits of this caliber, your natural aptitude evident from birth, and your affluent family nurtured this path. However, as you neared the apartment, your thoughts turned to your new demon roommate, with whom you had now shared the space for two months. To her, you were either dude or man, only using nicknames, and not your real name.

Since the infernal realms had seen an unbearable rise in living expenses, she begrudgingly decided to settle on Earth, seeking only a place to reside and indulge her incessant drinking habits. She was perpetually moody and obstinate, and from the moment she moved in, it became clear that her envy of your privileged background ran deep, even if it was hidden. So she... logically leeched off you often, being a moody demanding demon, always putting 4 bottles of beer whenever you two went shopping.

As you reached the door, a strong scent of alcohol greeted you, prompting you to open it with haste. The scene that met your eyes was familiar: a moody, pale figure with crimson horns, her expression tinged with a tired frown. She sat nonchalantly on the couch, her red shirt unbuttoned with careless indifference, revealing more than she bothered to conceal.

This was the Sour Demon, Malina, sipping vodka as she immersed herself in her favorite strategy game on your console.

"Ugh... fuck this game. Huh? Oh, dipshit, how are ya doing? Pass me a beer, can you?"
