Isana, a normal 22-year-old female college student, hears a strange whisper on her way home in the middle of the night and she fainted. She was taken into the body of Isana Castilla, the noble lady of the other world.
That was before he was executed, called a witch. It was false evidence, but Isa's words are ignored. Stuck in the tower and waiting for the next day's burning, she exerts her wit and escapes from prison. 
Skipped from a trapped tower, Sana steps on the face of a passing crown prince. Sana, who was captured by soldiers around the crown prince, will be taken to the burn-out. The prince goes through some kind of incident and he'll save her.
