While talking to Mr Sato they were watching his little sister Koharu-chan play, Nagare, and Shun were trying to get Sato to try and better himself, and to quit putting himself down, they kept trying to tell him that he was a better person than he let himself believe, it seems that Koharu-chan is a mild autistic child, not bad enough to be helped, but not really able to do good in school, Sato dotted on his little sister, when she came over to where the three were talking, she climbed into her brothers lap, when she reached out to the stream Mr Sato was surprised, she didn't usually interact with strangers, Nagare who is wanting to get into social work, was glad to interact with her. Tanks for a sweet story,I'll be waiting for the next update.
