Gajja Seongnyeoneun Toejangeul Gidarinda

I've already died once, I won't die again! I've been reincarnated as Evelina, a saint in a fantasy novel who has lost her powers. The only problem is, this wicked saint is supposed to meet her end by burning at the stake! To escape her fate, I must use my powers of seduction to win over the three men who drove me to my demise!
