Transmigrated into a Book as a Succubus, I Was Bought by the Saintess

[Yuri with two female leads, one-on-one romance + succubus + faux System + magic + transmigrating into a book] [Big-hearted, adorable little succubus vs. cool, aloof older woman with a warm heart] Everyone knows about succubi. You could say that every person and every race wants to get their hands on one. That’s why they’re so rare, to the point of extinction. Liu Mengyao thought it over. That’s right, she had transmigrated into a book, and there was no doubt about her race: she was a succubus. One of the last few succubi in the world. She could already imagine the inhumane treatment waiting for her. What a disastrous start!!! Liu Mengyao had even figured out how she was going to die, but who could have expected that a beautiful big sister would buy her? Yay!! A pretty big sister! I have to repay her!! She was already wondering whether to offer herself to her or work for free to pay her back, when she got hit with these cruel words: Ji Qinyue gave a cold “hmph.” “All succubi deserve to die.” ????????????????????????? (An endless string of question marks omitted here.) Liu Mengyao was dumbfounded. What does that mean?? You bought me just so you could kill me!!! She changed her mind. The first thing she’d do after being rescued wasn’t repay her, but run! Far away from this beautiful big sister who clearly had something wrong with her. Run!! She had to run!!! But Ji Qinyue was the former Saintess. How could a little succubus who hadn’t fully grown up possibly stand against her? “Run? Where to? Want me to take you there, little succubus?” Caught trying to escape? She was in for a world of trouble!
