葬花·暗黑桃花源

A man who lost his purpose in life enters a deep forest in a mountain region. He happens upon a strange cave, on the other side of which lies a mysterious village where everything looks as if frozen in time, completely unchanged since 2000 years ago. The people here are very friendly and hospitable, and the girl he encounters upon entering the village is of dazzling beauty... But what secrets can hide in this peaceful place? And why is it against the rules to leave your house at night?
