The narrative is paced by seasons or school terms, moving naturally from one emotional milestone to the next.

Why they belong together: These films are grouped together because they share a cozy ensemble energy, a seasonal or time-anchored structure, and a focus on multiple parallel romantic subplots woven through a friendship core.
