Renji Takahashi never thought his ordinary life in Osaka would end with him bound in a stranger's penthouse. But Valeria Moretti is no ordinary woman-she's a ruthless mafia queen, a billionaire with ice in her veins and fire in her touch. She gives him one rule: Love me in 365 days... or I'll make you beg to stay. Trapped in a world of power, seduction, and control, Renji fights to resist her. But every glance, every whispered promise, every touch drags him deeper into her twisted game. She's possessive. Dangerous. Unrelenting. And the most terrifying part? He's starting to want her, too. But love in her world comes at a price. One that might cost him everything-including his soul. A dark, addictive romance where love is a game of power, and obsession is the only escape.
