A Mansion Home to Enigmatic "Beautiful Girls" — Femme Fatales "Kouyoukan" (Maple Manor) stands secluded in the mountains, housing four devoted maids. The young author, Kusakabe Akira, stumbled upon this mysterious abode by chance, or so it seemed.

He came to drop off a letter from his late grandmother. But the head maid had other plans, handing him two unexpected assignments.

First, to stay as a "guest." Second, to pen a story set within these walls.

Caught in a creative rut, Akira agrees to the terms and becomes a temporary resident. He encounters four maidens, each bearing the name of a flower.

Life at the mansion unfolds leisurely, shadowed by underlying secrets. What discoveries and insights will Akira gain during his stay?
