Heres an Idea.. Maybe three brothers and one sister but a plot twist. The plot twist is that her lover was suddenly all a ghost and wasn’t real. She doesn’t realize that she has Charles Bonnet syndrome, which makes her see things that arent there. Her brothers play along with her to make her believe her lover is there. Then she will eventually find her own lover somehow and someway. YOU DONT HAVE TO USE THIS IF U DONT WANT TO. I ADDED SHE WILL FIND HER LOVER EVENTUALLY BC FOR A HAPPY ENDING
