Relationship analysis[edit]

Kogoro and Eri in school

Kogoro Mouri and Eri Kisaki are a married couple, who have been living separately from each other for ten years because of a personality clash. Despite being separated, they still love each other, although they will sometimes put on a show of disdain for the other. They were known to be a couple even in elementary school, making them childhood friends. It is a running gag that over the course of a case, one of the pair will come close to asking the other if they could move back in together, but then somehow Kogoro ruins the situation by doing something inappropriate or drunkenly flirting with another woman. Their daughter, Ran, tries to get them to hook up with each other by planning out ways for them to see each other out of the blue.[1]
