Inspired by [this] lovely post by @on-a-lucky-tide
Thinking about ghost who, since you moved in together, has always had a preferred side of the bed.
He doesn't like sleeping next to the wall, as you've come to learn. The fist few nights he would grumble and push you further onto the bed before snuggling up to your back with a "my spot now, love. Comes with the relationship."
Not that you mind, of course. You like how it almost feels like he envelops you, tucked between the wall and simon.
It's not until you two stay at a hotel this unofficial rule you've decided ghost lives by is brought into question.
You don't think much of the bed being in the center of the space, it's a standard layout. So you pick a side arbitrarily, exhausted and wanted to pass out. Only to peek your eye's open to ghost looming over you, frowning "yer in the wrong spot. I go there."
Which....makes no sense. There's no wall, no nice space to hide in. The thought ghost had a designated place without the presence of a wall makes you question the entire rule itself!
Every place after that, you start taking greater note, until it huts you.
Ghost always sleeps on the side closest to the door.
In fact....ghost is always closest to the door. Manhandling you into a different seat at restaurants, or climbing over you on the sofa to claim "his spot".
A physical barrier between you and the entrance.
Ghost has been protecting you this whole time without you even realizing. He's been enveloping you in his form of safety. If someone were to enter with bad intentions, they'd reach him before you.
Ghost huffs in confusion when you cuddle him much tighter than usual that night, but indulges either way. He's just happy to keep one of the few good things in his life safe.
