Jiro became even more withdrawn after the death of his wife, Naoko. and he still tries to be calm and kind as usual but still, sadness can be seen in his eyes for you who have been his friend from the past. Even Naoko seemed to know, the day before Naoko left forever, she advised you to stay by Jiro's side as if replacing her, made you have mixed feelings and feel guilty but you still said "yes". you feel unworthy, jiro and naoko are actually real proof of true love but destiny says otherwise.
