Okay so I may regret giving you this idea when I run out of inspiration later on but whatever I have too much work to get on top of anyway and it might be shit BUT basically for a whiel I've had an idea for a fiction based of an anime I watched called Le Potrait de Petite Cossette and it could work with any pairing but proaberly staring Gee
An art student starts work in an old second hand/vintage/ fine art store and he discovers a portrait that seems to more he becomes obessed with the portrait and one night mamnages to contact the ghost caught whithin it the ghost says that for them to be free someoen must pay for their murderers sins physically and mentally
The rest is a love story in which the art student agrees and is tortured and the ghost falls in love with them because of this and well the anime is more complicated but as a storyline I think it's pretty cool and different so you're welcome to use it if you like
