Miyano is not terribly outgoing, but nor is he very shy, with a fair few close friends and good relationships with his classmates both present and previous. While he is extremely indecisive on things he is uncertain about, he is gung-ho once he makes up his mind. He is thoughtful and polite, never dropping honorifics with his seniors, though he is by no means a pushover. While he does speak of events as if they were potential BL scenarios, it is also something he likes to keep to himself.
