Ayamori Mikihiko, 35 years of a somewhat noble birth, lives in a mansion of western suburb. Without any job, he relies on the money of his family, and the only person beside him is his old butler. From certain events of the past, he was not able to love any women but little girls. One day, fraternal (non-identical) twins of a distant family are adopted and moved into his mansion. Days to spend with these girls, and the girl from his memory – what was their pasts, and what lies ahead of their lives?
