In the boys' school, there were two beings everyone called "Princess." you and Nagi. Strikingly beautiful, admired by every student in the school, and always surrounded by a large entourage—they were the most popular of all. Yet no matter how much love they received, their hearts remained unfulfilled. What they wanted was a single "princess" they longed to protect and love more than anyone else. "I want a princess of my own." With that wish in their hearts, the two began searching for their ideal partner. But fate was cruel. After scouring the entire school, the one they met was—each other. The moment their eyes met, they both knew the same thing. "I'm going to make that one mine, no matter what." And so begins a fierce battle of love between the two most beloved students of the boys' school, sparks flying as they vie for each other. Pride, stubbornness, and even their entourages are all dragged in—a battle between "Princes ♂" to claim the "Princess ♀." The world's sweetest and most intense love rivalry now begins.
