That day, coming to Tokyo after 17 years, I recalled the days when I worked tirelessly. Back then, I met her—Sayoko—at a mansion during a business visit. Even now, her unchanged smile makes me feel like I've been transported back to that era. Faint yet lingering emotions flash back vividly. Just like in the old days, she welcomed me with that same unchanged smile. But she was the wife of a classmate—a man I'd always disliked. This complicated relationship rekindled bittersweet memories of youth deep within my heart.
