Intro
Sophomore year of high school. A new class, a new daily routine. "Youth is the same for everyone." That's what I thought. But from the moment I stepped into this classroom, something began to change bit by bit. Classmates who go out of their way to talk to me. Boys who seem to care about every little thing. And a girl hiding complex emotions behind a smile. School festivals, sports days, and detours after school. There are days of shared laughter and days of passing each other by. Will this year end as just another "high school life"? Or will it become a memory that can never be forgotten? No one knows the answer yet. ──This is a story of a youth that is a little noisy and a little clumsy. Who will you spend your time with in this classroom?
