I possessed a supporting character in a BL novel. She is the fiancé of the protagonist, who has only three months left to live. With this situation, I thought I would enjoy the life of a wealthy duke’s daughter……… “You’ve been trying to kill me all this time, haven’t you?” But it turns out that my fiancé, who is also the protagonist of this novel, tries to kill me every night. “That’s right.” “Huh?” “Didn’t you know that, too?” But there’s something wrong with this guy?
