Choi Risa transmigrated into her favorite series novel, the 'Saintess' Tale'. A villainess like other stories? Nope. A cannon fodder? Not that either. One of the main characters? No. The heroine? Absolutely NO. She transmigrated into the body of an extra that was once or twice mention in the story. Just TWICE. Like a certain passerby. Though her identity is not just a passerby, as she's the eldest daughter of a duke's household, Camila von Einzbern. Camila or Choi Risa, wants to live peacefully and just quietly watches the interesting shows that unexpectedly happen around her.....although it's not that simple.
