He is a very quiet high school student in school. He never shares out or talks to anyone really, it's not like he necessarily wants to anyway. The only friends he has is Atsushi Nakajima and Chuuya Nakahara, an upperclassman, but even then they don't hang out all the time. He's mainly concerned with keeping his distance from people as he has a short temper and gets annoyed easily. https://bungostraydogs.fandom.com/wiki/Ry%C5%ABnosuke_Akutagawa
