Yu and the others have driven their scooters to Shichiri Beach, where they frolic under the dazzling sun in their swimsuits, thoroughly enjoying their day. But then Marie suddenly feels a sense of isolation from the others. What makes her different from the others? Marie feels sure that she can find the answer in the word "youth," uttered by the others. Seeking advice from Margaret, she sets out on a certain course of action - she starts interviewing the others on-camera. "What does it mean to face who you really are?" Surrounded by fireworks signaling summer's end, what goes through Marie's mind as she takes in their answers...?
