Khimekawa is 26 years old and a beautiful bride that wants to remain a virgin until she marries. He lied her and said he had a career in the company when he actually works at a local store. Embarrassed and wishing to expand his career to get a chance to marry her friend (and virginity), Khimekava responds to the search ad and surprised by receiving an immediate answer. The answer comes from a dating company that wants to test its computer dating algorithm, and it is ideal for a reasonable IO-San. You can get a job in the company if you can confirm your algorithm, forcing IO-San to agree to marry him in a month!
