Cierra 

Cierra Elburke and Claude LeSpencer, both sharing backgrounds of illegitimacy, find refuge from the scorn of their family and society in each other’s arms. But when Cierra is forced to marry someone other than her beloved, she begs for another chance at life with a happier ending. Through the power of the “key” to the throne that is gifted by Claude, Cierra is given a chance to start over. Yet this time, she chooses to leave everything behind, including Claude, with hope for a better life. Has she made the right choice, or will this second chance prove more disastrous than her original fate? (Source: WEBTOON)
