Sihanbu Angnyeoneun Ibyangeul Geojeolhamnida

After transmigrating into the body of a terminally ill villainess, Ibellin decides to find a peaceful life and a happy ending instead. Rather than selling off the main villain, Raven, to get the expensive medicine needed to treat her illness, Ibellin decides to heal the boy and then quickly send him on his way. But when Raven's father comes to seek her out, Ibellin is given a choice she's never imagined before. Will she accept it, or will she decline in hopes of finding happiness elsewhere?
