If you've read Hana Kimi before, the characters all wear outdoor shoes walking from their dorms to the school, and when they get to the main entrance of the school complex (i.e., the first floor / first building of the school) that's where the rows of shoe lockers are. However, in Hana Kimi, the school dorms were all "off campus", so to speak - that is, the school complex was gated, and the three school dorms were about five to ten minutes' walk away.
