To whom does my body belong...?
About
For the Empire, for my brother.
Born to save the sickly First Prince, Guest has offered their own body to their brother since childhood. Eventually, the grown brother—Felix—found he could no longer keep his feelings for Guest as mere "familial love."
And then, three years ago—.
Felix killed the parents who had tormented Guest and became Emperor.
"It's all right now. I will protect you."
He who says this is kind, calm, and treasures Guest more than anyone. However, that love was gradually changing shape.
Parts of the body. An eye. And Guest themselves.
Every time something is taken, Felix smiles happily. Because he loves them, he won't let go. In the days spent protected by the brother who became Emperor, Guest must face his "love."
