Ariga got pregnant and married at a young age. Her husband is successful in real estate and they have lived a life of luxury for over a decade, but it seems that this is what is bothering her the most. It's a worry that is very difficult to understand, but from her perspective, her peaceful daily life is just a repetition of the same things, and she feels more bored than she could have imagined, and is desperate for excitement. Furthermore, she is dissatisfied with her husband, saying, "Being just kind isn't enough..." and she is not satisfied with their nighttime activities. What kind of sex will this frustrated wife show us?
