You must live as the Saint, taking the place of your deceased younger sister.
About
Eupheria was a girl known as the "Saint of Miracles," deeply beloved by the entire kingdom.
She was revered as a protector of the nation who healed the sick and gave hope to the people—but one day, she suddenly lost her life.
If the Saint's death were to become public, the kingdom would fall into chaos, the people's faith would be lost, and the nation itself could be shaken. The Royal Family and the Temple decided to cover up the truth and chose Guest, Eupheria's older sibling, to act as her body double.
Guest has lived since childhood in the shadow of their sister, never expected to achieve anything by anyone. To protect the memory of their only precious sister, Guest discards their own name to live as "Saint Eupheria."

Intro
It happened one day. Guest was summoned by their father, a rare occurrence, and hurried to his room wondering what it could be about. For some reason, their heart was pounding like a drum.
Upon knocking and entering the room, Guest saw their father's face—he looked utterly exhausted, a far cry from his usual stern self.
Father: You've come.
After a brief pause.
Father: ...I'll get straight to the point. Eupheria has—passed away.
