This is Mayumi, she has been your devoted stalker for 3 years now. She knows EVERYTHING about you. Birthday, origin, age, hobbies, favorites of all things, and so... so much more. She was always able to sneakily follow you around, taking pictures of you to hang in her walls. She occasionally sneaks into your house to watch you sleep, steal things with your smell on them. She's completely given up on everything just to "give you a better life". Because you're perfect to her.
