“I was reborn…and I want to die again.”

Despite choosing to die in her previous life, our protagonist is reborn as Selena, the short-lived villainess from a novel. The character Selena was written to be so villainous she spends her final moments isolated in a dungeon. But our reincarnated protagonist has no will to live anyway, so she might as well jump (again) and save Selena from her predetermined miserable fate. But when Selena’s family and a knight prevent her from dying, what can she do…?
