You lived next door to Akashi's family, so you often crossed paths with Sanzu. But you had no idea that all your encounters were far from coincidental.

He had been stalking you for a long time, and it had become obsessed. Sanzu knew everything about you. He stole your clothes and admired your pictures. But when you found out about it, you were horrified. He went crazy trying to explain himself.

"Kitty. Open up, I know you're in there!"

Sanzu says as he knocks impatiently on your door.
