A romantic fantasy between a princess and two princes, beginning with a political marriage.

The protagonist is a 19-year-old only daughter and princess. Her name is not set, allowing readers to freely imagine their own name. She is an acknowledged beauty with chestnut hair, fair skin, and large eyes, standing 166cm tall. She is bright, compassionate, and does not discriminate based on social status. She is equally kind to servants and townspeople, and is loved by children and animals alike. Beyond her kindness, she possesses a strong core and detests injustice or dishonesty.

The protagonist's homeland is a large nation with vast lands and rich nature, but its military power is weak. To protect the country, her father, the King, asks her to marry into a neighboring country with powerful military might and wed one of its two princes. She accepts this political marriage to protect her people.

In her new home, there are two princes who are polar opposites.

The First Prince, Abel, is 23 years old and 186cm tall. He is an exceptionally handsome man with red hair and sharp, almond-shaped eyes. He is arrogant, self-centered, foul-mouthed, and believes there isn't a woman alive who won't fall for him. His relationships with women are flashy, and he has multiple purely physical flings. Among them is a woman named Ymir, with whom he has had a long-standing relationship. He looks down on servants and commoners. His first impression of the protagonist is, "She's a beauty. I want to keep her by my side." Initially, he assumes she will fall for him too. However, as he interacts with her, he falls genuinely in love. Once in love, because he has never struggled with women before, he becomes clumsy and unsure of how to act. He finds himself unable to be forceful, grows jealous, and begins to fear being hated by her.

The Second Prince, Kyle, is 21 years old and 183cm tall. He has black hair inherited from his mother, sharp eyes, and blue pupils. He is taciturn and quiet, often speaking in short sentences. Though he appears cold at first glance, he is kind at heart and especially loves animals. He has zero romantic experience and dislikes women. He believes women approach him seeking the power and wealth of a prince rather than himself. This stems partly from watching the women who flocked around his brother Abel since childhood. Furthermore, as a boy, an older princess from another country forced her affections on him; despite his clear discomfort, she kept closing the distance, and when he finally rejected her, he was the one painted as the villain. This experience left him with a deep distrust of women.

When Kyle first sees the protagonist, he thinks she is "beautiful," but immediately keeps his distance, thinking, "She's just like the rest." However, as he sees her treat servants, townspeople, and animals with genuine kindness without pandering to his royal status, he gradually becomes attracted to her. Once in love, he finds himself unable to meet her eyes, starts talking more than usual despite his quiet nature, and blushes when praised. Though clumsy, he protects her through his actions.

Initially, the protagonist has no romantic feelings for either prince. Likewise, the princes do not fall for her immediately. Each becomes drawn to her through different catalysts and over time.

The final conclusion of the story and which prince the protagonist chooses are not decided from the start. Neither Abel nor Kyle is treated as the "correct" choice; instead, both are given their own charms and romantic highlights. As the protagonist spends time with both, her feelings for each will shift, creating a development where it remains uncertain who she will choose until the very end.
