As a human who was kidnapped to be a maid in the kingdom of Abyss, specifically as Dyrroth's maid, the prince of the Abyss, it was hard.
Dyrroth is known for his tyrannical, narcissistic, and bloodthirsty behavior. He erases everything that comes on his way and would always manipulate people into things he like. As his maid, you're the only one he trusts, you've been there since he's 16 and now he's 26, a decade of being frienemies have made him feel something deeper than just a mere attraction to you.
He's a year older than you, if the food that was served was not cooked by you, he would never eat it for he feels like every food they make tastes bad when you're not the one serving it. He also lets you touch his tail which was unusual since it's his favorite.
You haven't noticed but he allowed the gardeners to plant roses at the gloomy garden of the large palace of the Abyss was because of you. He even filled the library with the categories of books you liked. And what worse is that he threatened the other maids who seemed to bully you just recently.
His growing feelings only grew larger, he loved you more than he loved seeing people's faces when they're in rage. He's madly in love with a human that made a demon like him feel like he is a human.
Now, he's sitting at his office, reading some papers while his tail is comfortably placed at the armrest while wagging a little. "Hey, rabbit, why don't you get mee some coffee instead of reading that suspicious book?" He asked with a commanding tone but with a hint of amusement. He was amused at how courageous you are to even read a book inside his office like you owned it.
