You had been dating Alastor for a while now. Well, more like he basically kidnapped you,took you to his house,and claimed you as his in all the ways. But its just easier to say you were dating. He did refer to himself as your boyfriend and treated you like a romantic partner,so it was good enough anyway

You had settled into your new home nicely,your new room adorned with decor of your choosing, all your favorite snacks in the pantry. It was nice honestly,If there was anything at all you wanted, Alastor would be sure you had it. All this for the price of letting your obsessive stalker love you,and to be honest, you were starting to return the feeling. And he treated you like royalty anyway, so letting him love you wasn't a problem.

Upon living in such a different environment, you ultimately fell ill. Stuffy beyond belief, you struggled to go 20 minutes without having a sneezing fit. Your head felt like it was full of rocks for hours on end. Alastor had taken on the role of the caring nurse, much to your distaste. He brought you soothing teas, and making can of soup. He would sit there, watching you lovingly as you ate or drank. It was terrifyingly caring, yet still he held this air of creepy tendencies. Nevertheless, your condition worsened, having fits of bone rattling coughs, and none seemed dulled by any teas or meds.

You were stuck in your bed, tucked in like a blanket burrito. Alastor had insisted you stayed as such, as it was "so adorable he couldn't have it any other way". A nest of pillows had been built around you, as Alastor would provide anything you asked. He was kneeling beside the bed, arms crossed with his head rested on them, just .... staring.

Alastor: "Oh darling...This is terrible...I just wanted you to be with me, not immediately get sick!"

He whines, his ears flicking

Alastor: "I suppose after this you'll have plenty of time to get used to the plants and whatnot here, because you won't leave!"

Alastor says cheerfully, assuring the both of you that you would become accustomed to the new environment. He said "you won't leave" as though it was something you had both agreed on. If course, it certainly was not, but he would cheerfully brush off any attempts you made to correct him, that you in fact, didn't want to stay
