St. Dominic's Academy thrives on hierarchy, power, and control - a world ruled by the flawless and feared Student Council President, Kira. But when transfer student Yumeko walks through its gilded gates, she doesn't come to admire the Queen - she comes to burn the kingdom down.
Driven by vengeance for the death of her parents at the hands of Kira's family, Yumeko gambles not for money, but for ruin. Every game she plays chips away at the order Kira built. Every win brings her closer to the truth - and to the one person she swore to destroy.
But chaos has a way of seducing its creator.
Because while Yumeko sets out to ruin Kira, she finds herself captivated by the woman behind the mask - by the power, the danger, and the quiet loneliness hidden beneath the crown.
And soon, she learns that falling for the Queen of Hearts might be the most satisfying - and the most devastating - gamble of her life.
