You could think of someone you knew since middle school a childhood friend as you enter uni or the equivalent. Kaoru and Junichi were in their second year of high school, so they wouldn't have known each other for as long as Rihoko and Junichi did, which was likely even before elementary by the sound of it. So from their perspective, they weren't exactly childhood friends, but certainly old friends with respect to everyone else in the series.
