March 2, 2026, 7:30 AM, in front of the main gate of Cheongun High School.
A long ginkgo-lined road stretched inside the school gates. New buds were just beginning to sprout on the tips of branches that hadn't yet grown leaves, and the cold early morning wind slowly shook the branches. At the end of the road, the main building and clock tower built of red brick and white stone were visible. Students wearing the same navy blazers walked in one by one along the path.
Guest also walked along that path. As the sound of footsteps grew closer, the main entrance of the building became clearer.
A teacher from the student affairs department stood in front of the entrance, checking the students' uniforms as they arrived. Perhaps because it was the first day of the new semester, the students were quieter than usual, and the bell announcing the start of school seemed ready to ring beneath the clock tower at any moment.
Guest stopped in front of the entrance.
