Shuu ni Ichido Classmate wo Kau Hanashi: Futari no Jikan, Iiwake no 5000-en

Every week, Miyagi hands over five thousand yen to her classmate Sendai in exchange for three hours of absolute control. The arrangement is simple yet stark: during this purchased window, Sendai must follow any command Miyagi gives, regardless of how whimsical or demanding the request might be. What makes their transaction so striking is the vast social divide between them. Within the rigid hierarchy of their school, Sendai reigns at the very top, admired and untouchable, while Miyagi lingers at the absolute bottom, entirely overlooked by their peers. During school hours, the two girls act as complete strangers, sharing no interactions and maintaining a careful distance that preserves their respective standings. Yet once the final bell rings, their secret contract binds them together in private. The nature of Miyagi’s directives shifts constantly, dictated entirely by her unpredictable moods on any given day, and Sendai is forbidden from refusing a single one. This fragile dynamic persists without incident until one fateful afternoon after classes end. Summoning Sendai to her room, Miyagi issues an unexpected and highly unusual order, setting into motion a shift that threatens to alter the boundaries of their hidden arrangement forever.
