Koutarou Miyao

Koutarou Miyao is Haruo Yaguchi's best friend, having known him since middle school and attended the same school with him through high school. He cares deeply about Haruo, supports him when Ono and Hidaka confront him, and seems uncomfortable around the two girls because of their feelings for Haruo. His words and behavior also suggest that his own feelings for Haruo may extend beyond ordinary friendship.
