Miyokichi Nobuse

Miyokichi is Shin'ichirō's good friend, and has known him since they were kids. They hang out together at school, and Miyokichi often brings up the fact that Shin'ichirō has an eye out for Hiromi when at school. Shin'ichirō introduced Miyokichi to Aiko which eventually led to Miyokichi asking out Aiko, and she agreed, though it is apparent that she agreed reluctantly. He did not seem to notice that Aiko has feelings for Shin'ichirō until she revealed it to him in a subtle way. In the end, Aiko wanted to start all over again with Miyokichi.
