The Emperor's Partner

After learning that her younger sister sacrificed her own life to save hers, Shinju dies saving a child that reminds her of her lost sibling. On the brink of life and death, she pleads that if there is a god, that he may give her a chance to repay her sister one last time. Her prayers are seemingly answered when she is reborn into a new body in a new world. But before she can find her sister or even attempt to understand what happened, a strange man kisses her in front of hundreds of people.
