When she wakes up she's inside the novel she read before she lost her sight, reincarnated as the Villainess, Ariel. Ariel is a genius perfumer, but has a rotten personality. She forced the ML into a relationship with her, by holding hostage the special perfume, that only she can make, which keeps the ML's curse/madness at bay. In the novel Ariel's villainous actions gets her killed. So, to destroy her deathflag the new and improved Ariel's first action is to break it off with the Duke. Next she plans start her own perfuming business to stave off her father's plans to marry her off to someone awful.
