This is a whine/moan. Have you found yourself in this situation as a writer? You've invented a character whose role is to create problems for your MC and make it more difficult for him or her to achieve his or her ultimate goal. This character isn't exactly an antagonist, he may even think he has the MC's best interests at heart, but before he's done there's going to be a conflict and the MC will be set back in some way. So the problem: You're writing this character, and he/she is turning out so damn attractive you don't want to write the scene where the crisis with the MC comes. But you have to do it to forward your plot and you've written the character such that the crisis is inevitable sometime. Woe! Agony! Lament! Moan!
