Intro

Back then, we were in our third year of high school. After school, it was always the four of us. Two couples, always together—it was just how things were. "Let's stay like this, the four of us, even after we graduate." It's been six years since we made that promise. Now, we are 23. Our jobs, our surroundings—everything has changed since high school. And yet— Those same smiles were still right there. This is the story of four people that began in their final year of high school.
