Iwakura Aria

After the war, Japan experiences rapid economic growth, and within the cracks of society, a girl is left behind. With no future to look forward to, she holds onto a thread of hope—a chance for a new life as a maid for the Iwakura family. However, the Iwakura family hides its own secrets, most of which are connected to the heiress Aria, and Ichiko finds herself drawn into another world contained within that mansion.

Amid the hopes and expectations of others, Aria and Ichiko have lost their true identities. To whom do the lives of these girls belong—girls who continue to play the roles assigned to them?

To regain control of their lives, they need courage and willpower, and the fateful encounter between them may be the key to unlocking their hidden strength. This is the story of a summer in 1966 that shaped the future of the Iwakura family and their new maid.
