I think why the ending showed than still young is that like their feelings never changed. And y Satoko didn't find Shinpei was that she was maybe not healthy enough and y he didn't get any letters from her was because after he thought she died he like travelled and didn't tell anyone his name so I think that's the reason y Satoko couldn't find him
