Riiko, a young high-school student, has had a tendency to buy a lot of goods from street vendors and merchants, but then she realized she was being scammed each time. She made a vow to herself that she would never buy from another street vendor again.
While walking through the park, Riiko comes across someone's cell phone and when she returns it to the owner, he asks her if there is anything he can do in return for her kindness. She asks for a boyfriend. The man gives her a business card with a URL to visit. The site he sends her to is a place to make your own subsitute boyfriend. You can make him charismatic, charming, sexy, a good cook, whatever you want.
As Riiko starts to enjoy her relationship with her new boyfriend, Night, another boy is starting to have feelings for her. It turns out to be Soushi, her childhood friend and neighbor, and Soushi starts to become agressive and jealous over Night.
