Anyway, Rizo has a strong sex drive and gets dumped by her boyfriend because of it. Meanwhile, her younger brother Takero quits his job due to bullying and becomes a recluse at home. Rizo discovers a handwritten shoulder rub ticket that her brother gave her 10 years ago. While trying to cheer up her listless brother, she comes up with an idea to satisfy her own sexual desires. She shows him the shoulder rub ticket and says, 'As a thank you for the shoulder rub ticket, here's a vagina rub ticket. Use these and cheer up,' as she hands Takero 10 condoms.
