Kyoko is at the autumn of her life.

She can barely recognise her own family member. But one day, someone she remembers perfectly comes to visit. Her name is Mitsu, the woman Kiyoko had a love story with. Just after the war, when they were still teenagers, they nearly did the irredeemable out of passion.
Despite a few meetings from time to time, life ups and downs separated them, but the story draws us back in the time when they couldn't imagine life without each other.
