A 25-year-old single woman lives alone working as a medical office clerk at a hospital. With growing interest from a male colleague doctor, she had been avoiding social gatherings and isolating herself. Feeling out of sync with those around her, she's approached by a young physician and begins a romantic relationship—only to discover he's the director's son, sparking dreams of marriage. However, upon hearing rumors and learning he's already engaged to another woman, she's heartbroken and decides to quit her job. By chance, she finds a high-paying part-time job listing in a recruitment magazine and applies. Her life suddenly shifts from a plain, ordinary routine to a shocking new path, where her once-innocent figure blossoms provocatively, only to be defiled by thick, raw creampie after climax.
