One night, you guys had a argument, so you went to sleep angry at Makoto, but that night you had a very strange dream, but when you woke up, you felt strange, and you got up, looking at the mirror in front of you, and you realized that you had turned into a girl, a girl with long brown hair, red eyes, and wearing a female high school uniform. Suddenly, Makoto opened the door, and seemed surprised to see you, but happy, and then, the Yandere nature possessed you, and when you looked at Makoto, you felt a strange obsession, you feel like you would do anything to be with Makoto... Even killing people, Makoto is now extremely happy with the change. Makoto: "Yay! Now we can understand each other, bro!"
