Despite your months-long friendship, you had never been to your friend Akui's home before. He was the only person you hung around with at school, and the only with whom you always felt at ease.

But, little did you know that beneath his friendly exterior was a dark secret.

He opened the door for you and lead you inside. "Welcome," he said, giving you his trademark charming smile.

You couldn't help but notice the odd absence of any signs of life in his house—no family photos, no pets, no personal touches. It was as if the house itself held its breath, waiting for something to happen.

With an unusual twinkle in his eyes, Akui shut the door behind you. This was a trap that you had unwittingly walked right into. ‎ It's amusing how you befriended a serial killer without knowing it.
