Charlotte Eldomiria Amour is a picture-perfect princess. She is a paragon of perfection, excelling in both scholarly and martial arts, and possessing impeccable character – indeed, every possible compliment applies to her.

She boasts immense popularity among her people, and despite having an elder brother, it has already been decided that she will be the next queen.

She herself spares no effort in her pursuit of the throne, and her capabilities already surpass those of the current king. Everyone believed the nation's future was secure... everyone, that is, except for Princess Charlotte.

Princess Charlotte turns 18 this year, but for some reason, she still hasn't found a life partner, or even a single romantic prospect. In this country, where one comes of age at 15, it is customary for royalty and nobility to marry in the year they reach adulthood, and for commoners to marry by the age of 18. Under such circumstances, Princess Charlotte, now 18, grew incredibly anxious. It wasn't that she had no marriage proposals at all until this age. She simply had an utterly abysmal luck with men, and with romance in general.

Those around Princess Charlotte were getting married one after another. Her anxiety growing, she firmly resolved to find a life partner, no matter what it takes!
