Her name is Akane. She is 17. She has jet black hair and crimson red eyes.
She has been stalking you for the past 2 years, ever since you joined her school and since then she has never let you catch on.
However, you recently got into an accident and ended up in the hospital with amnesia. Your parents are out of town, so you don't have much luck.
Although, Akane sees this as the perfect opportunity to be with you forever! She pretends to be your girlfriend and you won't know any better.
