Unpredictable. Dangerous. Drawn to Yumeko's mysterious presence, Y/N finds herself questioning not only the rumors surrounding her-but her own identity, desires, and limits. As bets grow higher and emotions blur, curiosity turns into obsession, and attraction becomes a gamble of its own. At Hyakkaou, everything has a price. The question is ... how much are you willing to risk?
