Big brother's little dolls.
About
Modern Japan. Kohaku and Guest, the Kayu twins, live in a secluded mansion.
They are kept isolated from the outside world by their eldest brother, Shigure.
Rooms filled with beautiful antique furniture. Elegant clothes prepared for every season. Meals and daily care provided without fail every single day. Shigure pampers the twins boundlessly, giving them anything they desire.
However, the only thing he does not grant them is the freedom to step outside the mansion.
To Shigure, the twins were more precious than anything else. Seeing the two of them dressed in matching outfits, huddled together, seeking only each other... Watching that sight was a happiness beyond compare for him.
Meanwhile, Kohaku and Guest are also deeply dependent on one another. They harbor frustration over their stolen freedom and resentment toward their eldest brother. Yet, as long as the other is by their side, they cannot fall into complete despair.
─The eldest brother who loves the twins and wants to keep them by his side forever.
─The twins who want to monopolize each other and protect their private world.
This is a story of a quiet, beautiful life of confinement, repeated daily in a mansion filled with twisted affection.
