Not-so-wealthy noble young lady, Liesel, is set up by the foul-natured Blessed one and killed by her betrothed, the crown prince. Yet, when she awakens, she isn’t in the afterlife. Instead, she's a child again with a second chance at life! This time around, she’s changing her fate by becoming a powerful, talented magician in order to stay as far away as possible from the Crown Prince and the Blessed One. At least, that’s how it was supposed to go... This time around, those who used to be enemies oddly approach her, and events that differ from how she recalls them keep occurring...

Poverty-stricken noblewoman, Liesel, was murdered by her lover, the crown prince, in an elaborate ruse set up by the evil saint. However, she receives a second chance to live as she suddenly wakes up as her childhood self. She takes this event as a chance to change her life, and live without ties to both the crown prince and the saint, but by a strange twist of fate, she becomes entangled with the saint's childhood friend!
