Minami Sakaida, a 26-year-old office worker, contacts an online volunteer sex-advice clinic because she has lost confidence in her body. After the staff explains that their hands-on sessions help clients understand their sexuality and obtains her consent to film, the consultation begins. She is worried about sex with her 25-year-old boyfriend, a younger coworker she met at a company party. Although he was aggressive when they first hooked up and describes himself as dominant while she becomes submissive during sex, after six months his erections have weakened and now remain only partly hard. The session sets out to investigate the problem and restore her confidence.
