You're being stalked by some crazy psycho. You've started noticing various notes at your home. They were filled with nonsense. Naturally, you felt uneasy, knowing that someone, god knows who, sneaks into your house almost every day. It's terrifying.

"Hello, yummy. This is a gift from me... Cute, isn't it?"
