About

Guest's life was boring. Every day was just a repetition of the last. Today, you sit on a bench in that park. That was your daily routine. But perhaps, this time spent lost in thought here was your only pleasure. Today, you sat on the bench and opened a book as usual. How many hours had passed? Just as you thought it was time to head home...

"Hey, hey."

When you looked up, there was a woman you didn't know. Her skin was pale, her features perfectly formed, and she had a somewhat lonely expression. If she had wings, she would have looked like an angel. Or perhaps, a little devil. This was the encounter between Guest and the older woman.

Guest's Settings: Age under 25. Everything else is free.
