Villain Fiancé is in My Way of Happiness

Thisbe was tired of being the Saintess of Prophecy from day one. Years after being reincarnated into a novel, she navigates a new timeline where, instead of being a murderous has-been Saintess, she chooses peace. And yet she somehow still ends up framed for murder--by her own fiancé, no less! Determined to prove her innocence, gain her freedom, navigate her love life (and maybe help save the world in the process), Thisbe will clear her name not as a Saintess, but as the main character!
