FICTIONAL CHARACTERS LETTERS

Imagine your F/O learns to braid hair just for you. They overhear you complaining about how annoying it can be to do it yourself one day and by the next evening they've already watched way too many youtube tutorials on how to do it. They even got a wig from the nearest store to practice on while you're away. All so that they can surprise you the next time they see you. They have you come sit between their legs, brush your hair gently, probably sniff it subtly because they love the smell of it, and then start carefully braiding it. They do such a good job that you're genuinely shocked. They get sort of embarrassed to admit how much research they did and insist it's no big deal and you're worth the effort.

F/O QUESTION OF THE DAY

If an evil witch appeared right now and turned your fictional other into an animal, what kind of animal would they be and lowkey do you think they'd enjoy it? Like, would they be desperate for you to find a way to turn them back or would they be like "Wait let me crawl into your lap for some pets first"?

Imagine your F/O cleaning up your bedroom for you while you're out of the house. Like, you left in such a hurry so your clothes were scattered all over the place, and you were dreading returning home to a bed you wouldn't even be able to lay on. But now you get home to find everything perfectly tidy and your F/O is waiting for you in your bed. Maybe they even bought you a new set of pajamas to get changed into. Just being taken care of like that and not having to worry about menial tasks is so yummy.
