Naoh is a housewife with a busy daily routine, while also working part-time as a fitness instructor at a sports club. Many of her friends are athletic men, one of whom invited her to a drinking party. According to him, Naoh's husband is occupied with work and they rarely have sex at night. That's why she started looking for encounters outside and took up the part-time job. She enjoys drinking and genuinely has fun at parties, but deep down, she craves sexual fulfillment. When secretly asked out on a date, she readily agreed. Through smooth, natural conversation, their relationship gradually grows more intimate.
