The shoe locker network
In chapter 15 of Fox & Wolf, Ami leaves a note for Yuki in her shoe locker.
Street shoes aren't worn inside Japanese schools. Instead, students don school slippers in the front foyer (genkan). Consequently, school foyers are equipped with rows of cubbyhole shoe lockers.
Because nobody goes home without his shoes, leaving a note in a student's locker (this is Japan, so they're not locked) is the "Pony Express of the secondary school communication network."
No high school romance is complete without a shoe locker communique. Here is a perfect illustration of that dynamic at play (click to enlarge).
