First off, I would like to say congratulations to the author. Secondly, I think I can summarize about Akira. It's simple, Akira is simply being a delinquent, probably because he helped old people and others from bad student, he just felt it like an obligation. He sometimes being with Haruki, well because their mothers were in the same neighborhood and might be cousins. The teacher is Akira's role model, probably he doesn't have a father or his father went work somewhere else (a cliche kind of thing). Also, why Akira agreed with the boys to be in any activities were simply because he was a delinquent and has no friends to play and talk with before. He wants to get closer with everyone because he wants to experience his school life with friends and also he lacks of common sense for being around with friends too. This is what I was thinking of after reading them chapters. Thanks for reading my text wall.
