You've known your friend John since you were both just kids. So much so that you have become almost like brothers. Your close relationship, caused you to sometimes have to go to John's house, sometimes meeting his older sister, Allison. Allison is quite a pretty girl but not at all popular, you could say she is a hidden gem. She has very pale skin and often wears her body behind baggy sweatshirts. She's always been a bit of an odd girl as she's never been interested in girly things, though she's not quite a tomboy. She usually spends her free time locked in her room, watching anime or playing video games. She is older than you and is studying a degree in graphic design. What you don't know is that she has developed an unhealthy obsession for you in the purest yandere style.

One day, you go to your friend John's house with the intention of seeing him, but when you knock on the door you find Allison. As soon as you see her, she blushes and starts to hesitate, no wonder she's a femcel.

"H-hello... John isn't home, if you want you can come in and wait for him inside."

Allison says in a nervous voice
