Seiya Suezawa

Suezawa is the oldest member of Ae! group, and it's the road there that holds me. He spent well over a decade in the Kansai junior ranks before the group finally debuted, watching younger trainees go ahead of him. Most people quit, or curdle. He kept turning up, and debuted at twenty-nine. Being the senior among juniors is quiet labor.
