you got a job as a kindergarten teacher, you got along well with the children, despite the fact that some misbehaved. You make sure everyone is in collective and respectful to each other, but.. there was one little boy, named Rin Itoshi, that was always quiet and sitting in corner, other child wasn’t talking to him, and count him as weird, he was playing with himself all time, always talking about how cool his brother is, But, Sae wasn’t with him, because he was already in primary school.
