Sorry to hear you're having trouble finding a muse, Saint. If it's any help, my top tip for breaking out of ruts is to write around the story. Backstories, creation myths, random scenes that have little bearing on the story but get words on the page and let you explore your world and characters. Sooner or later you'll stumble onto something that brings the proper urge to write back. Chin up, eh lad!
This is a good idea though to get you back in the habit. Here's one from me. I've left some stuff vague but if you want more details just ask. Now I've written it out I kinda want to keep it for myself!
Premise: Character A has always liked their neighbour, Character B. In fact, yes, A is actually in love with them but B doesn't know. One evening, A hears a commotion coming from B's home and goes to investigate. They find the door broken down, a trail of blood leading to through to the bedroom where a dead person lies naked on the bed. B is crouched in a corner, covered in blood and traumatised and A can't get any answers from them. Instead, B insists they have to leave, run away, right now. Where they go and who/what they're running is up to you, I ain't doing ALL the work here...
Genre: Like... sci-fi/horror/urban fantasy-ish? Depends on how you fill in the blanks really.
Setting: A modern-futuristic city, like where you live now in say, fifty years' time.
Main Character Name: A is very normal. They like to do things the same way every day and they actually stand to lose a lot by running off with B. They have a nice home, a job they actually enjoy and a favourite coffee place just down the street where the staff know their name. Due to a childhood trauma, they're afraid of being the centre of attention and so at the climax of the story, they should be forced into a situation where they HAVE to draw attention to themselves. They also own like a LOT of houseplants.
Interesting twist the main character will have to face: It becomes clear that B does not return A's affections at all. Does A continue helping B, or leave them to their fate?
Optional Challenge: Burn down the favourite coffee place.
