Number 21: Ghosts in Love!AU
Eddie was a groom to be but on his wedding day he found his finance in the arms of his best man (just like a soap opera this) in a rage he attacked him but was fatally shot by his wife to be, she was a jerk and had been using him and had planned on offing him at some stage.
Due to his strong emotions at the time of his death Eddie came back as a ghost. Scared and on the verge of losing himself and becoming a demon he met another ghost; Waylon who was a young man who died after a mugging gone wrong. He managed to calm him and show him that being a ghost isn't all that bad. After sometime they finally fall in love with one another and are able to pass on together~
Eddie is a banshee as he had his heart broken, so he cries a lot and that causes issues with living people while Waylon is a poltergeist so can interact with things in the living world and create ghostly apparitions.
