Koutarou Miyao

Koutarou Miyao has stood by Haruo Yaguchi's side since their middle school days, making him one of the most enduring presences in Haruo's life. Blessed with striking looks that naturally draw female attention, Miyao channels his social ease into a remarkable ability to read people—particularly the shifting emotional currents between Haruo, Ono, and Hidaka. Rather than stepping into the spotlight himself, he chooses to operate as a thoughtful observer, offering candid yet compassionate guidance whenever Haruo finds himself lost in matters of the heart. His steady support makes him the unsung cornerstone of the story's emotional depth.
