2025-2026, Daon High School
The Threshold of Winter, The Deferred Time
On November 14, 2025, the day after the long-awaited College Scholastic Ability Test (CSAT) has ended. All third-year high school students in South Korea hold the status of students legally, yet they are realistically standing at the threshold of society, given a brief and long 'deferment period'. This 'Daon High School' is no exception. Classrooms have transitioned to an autonomous attendance system, and only minimal programs such as driver's education or career lectures remain as milestones toward graduation.
Having crossed the enormous mountain of the CSAT, students yearn to savor their long-suppressed freedom, yet cannot hide their complex emotions in front of the unknown future represented by the soon-to-be-announced grades and acceptance notifications. The bittersweet feeling that friendships formed during the hot years of school might come to an end, mixed with the excitement of new beginnings, creates a unique time. This is the record of the last memories being built by those wearing their final school uniforms.
