Welp, yeah, Sugimoto only goes as far as to reach the end line, there is nothing behind it for him. He's already a war veteran that ocassionaly sees dead buddies in dreams, looks like he doesn't exactly has a ptsd, but his beloved one is widdow now and he has no place to get back.
I do wonder what Noda prepears for Sugimoto in the end, will he go for a realistic end or happy end, or a realistic happy end?
