Lua was a candidate for sainthood with the gift of healing. However, her powers had one flaw; she could only heal others by transferring their wounds onto herself. This made others mock her, giving her the nickname "Fallen Saintess." Despite this, Lua remained unbothered because her best friend Arianne always supported her. One day, Lua's crush, Commander Garrett, was critically injured in a beast attack. She healed him, but it came at a cost - she nearly died herself. When she woke up, she learned that all the credit for his recovery was given to Arianne, revealing her true nature. Devastated, Lua felt helpless until the second prince approached her with an enticing offer. What would become of Lua as she embarked on this new journey as a villainess?
