We've been married for 7 years. Aki, a beautiful wife, is on good terms with her husband, but is growing frustrated with her husband's bland and short sex. In order to relieve her dissatisfaction, she is masturbating, and the man who is asked to manage the apartment complex witnesses her embarrassing scene. Due to her embarrassment, she tries to avoid him, but before she knows it, she starts talking to him about her sexual problems... The two of them are attracted to each other for some reason and are married.
