"I never thought my life would end up a choice between happiness and ruin...!"

Stellacia, princess of Saint Gaia, has been shunned by her father and half-brothers ever since the death of her mother, who was a concubine. Furthermore, by her father's orders, she is forced into a political marriage with the prince of the rival country, Planed. Abandoned as a political tool, she is not welcomed in her new home as a princess of a rival country...and then collapses from hunger.

It is during this time that she has a "dream." It is a memory of her previous life, when she was sickly and short, and of the time when she was "reborn as Stellacia."

God says that Stellacia's soul harbors a "star of ruin," which will ensure her life is short even if she is reincarnated. However, she is told that she will have a chance at salvation in her next life. Two candidates for her "soulmate" appeared before her, and if she chose the right answer, she would be blessed, but if she chose the wrong answer, she would be doomed!

When Stellacia woke up from her dream, she couldn't believe it... but just as predicted, two princes appeared, and she was asked to choose one of them as her husband...!?
