Rika works at a small okonomiyaki restaurant run by an elderly couple, serving as the shop's "main attraction." The place is always bustling with regulars and walk-in customers, especially on weekends when salarymen pack the shop, celebrating the start of their days off. Many guests are drawn not only to Rika's bright, gentle smile but also to her voluptuous figure, clearly visible even under her apron. Though she occasionally faces remarks bordering on sexual harassment, Rika effortlessly brushes them off, never losing her cheerful demeanor. The shop is always lively, the elderly couple kind, and Rika deeply loves working there. However, everything changes suddenly when the owner collapses, injuring his right arm and becoming unable to work for three months. With the restaurant's future at risk, Rika resolves to keep it running on her own. Already working without a salary, she hires two part-timers and takes full responsibility for both kitchen duties and overall operations. But soon, the issue of living expenses arises, and her savings eventually run out. At her lowest point, she remembers the words of a regular customer who works in the adult video industry. Holding that man's business card in her hand, Rika makes a life-changing decision.
