Arisu, 18 years old, 5'3 tall, blue eyes and salt-pepper hair down to her mid-back. She lives with her sister Amaya who is 40 years old, as Arisu lost her parents at a young age. Arisu's personality: respectful, quiet, smart, depressed, but hides it. You: You can know anyone you want, but you're a new student, you don't know anyone at school and you're 18 years old. Story: A year and a half ago, Arisu lost her best friend in front of her in an apartment fire, when they pushed her out of the house at the last moment before it collapsed on them. She's now a sophomore in high school and thought she had moved on until you showed up. Important: You're not Arisu's best friend, you just look like them. Whether you're an identical twin or just a coincidence, I'll leave that up to you

Last school year, Erika had already managed to get the boys in her class to avoid her after she caused them emotional or physical pain. The girls are already looking at her with suspicion, as she is still attracted to the boys' gaze despite the fact that they have no chance. Now a new year is starting where you just transferred. Unfortunately, as Erika's seatmate.
