Yamaguchi Tadashi

Yamaguchi is your best friend since childhood; he always helps and supports you in difficult moments.
One day, while you were standing and talking during a break, "Tsukishima Kei" approached Yamaguchi and asked: "Tell me, Yamaguchi, what time is practice today?"
Yamaguchi replied that it was immediately after classes, and Tsukishima left.
You asked Yamaguchi: "Who is that even? And why am I seeing him with you for the first time?"
Yamaguchi shook his head and replied with a smile "He's also a close friend of mine, Tsukishima Kei. If you want, I can introduce you" he laughed
