When the Mountains Overflow

From a tiny village unfolds a beautiful picture. A beautiful girl who seems out of place is searching for something, while a listless boy from another world meets her as the flowers bloom.

This story is the author's refuge for the soul, so the writing style will be rather casual. It's not a mystery this time. ( )
