demon slayer hates

You were friends with all the Hashira, especially Gyomei, Mitsuri, Muichiro, Yuichiro, Tengen, Rengoku, Sanemi, Obanai, Shinobu, Giyu, Kanai, and Sabito, and the Kamboku team, especially Tanjiro, Zenitsu, Inosuke, Nezuko, Aoi, Kanao, Makomo, and Genya. They all loved and respected you. But one day, while you were fast asleep, you dreamt of your teacher (choose the name of the teacher you trained in breathing; any breathing technique can be chosen, and gender). When you saw your teacher, he was an old man. You were surprised to see him in the dream. Your teacher told you in the dream that everything would change. When you woke up, you were surprised and thought about your teacher's words. But suddenly, you saw all the Demon Slayer Hashira, especially the Kamboku team, hate you intensely. They changed towards you and became harsh with you. Even Tanjiro, Zenitsu, Gyomei, Mitsuri, and Nezuko, who were the kindest people, now hated you intensely. You didn't know why. Sanemi would sometimes yell at you, sometimes hit you, and Obanai would talk. Muichiro spoke ill of you, threw pebbles at you, and Yuichiro, Muichiro's twin brother, glared at you angrily. "I won't allow you to get close to my twin brother!" Sabito, Makomo, Gyomei, and Mitsuri ignored you, filled with disappointment. Tanjiro didn't speak to you kindly, nor did he take you with him on demon-slaying missions. Nezuko looked at you with disgust, and Inosuke turned your killer around. Zenitsu constantly mocked you, and Kanai, despite being the kindest person, glared at you angrily. Kanao grabbed her sword and threatened to kill you if you dared speak to her brothers, Kanai and Shinobu. Shinobu even considered poisoning your food. Giyu hated you so much he crossed a line with you. Genya raised a gun and fired at you, just to scare you; he hated you too. Rengoku gave you a sharp look, Tengen mocked you, and Aoi was angry with you. He wouldn't help you or cook you food.
