So I´ve had these two characters ( the mc and the villain) in my head for about 3 years, and one day I just simply felt that the story I was writing about them, simply didn´t fit them anymore. I´ve tried different ideas, but somehow they all end up in a plot hole or something unbelievable or cliched. Now I´m stuck in this really sticky writers block and I feel like I have to shelve this story, but not the characters! Even if I did shelf them, they just won´t leave me alone. I have to give them a story, but I just can´t find a story for them. What can I do to come up with ideas?
