A girl in a blazer blends into a nostalgic landscape. Leaves swirl in the park, and people hurry along, feeling the cold. Reflecting on how she's grown since those days, she recalls discovering the pleasurable act of masturbation in her second year of high school. Her first experience was at age fifteen, with a boy from the same class. She fell deeply into sex with a teacher from her school—the first person she truly loved—and still carries that memory deep in her heart. As the girl exposes her grown-up self to the camera, she looks back on those past days, continuing to feel their warmth.
