Every morning of the 11th, a 71-year-old man named Toshihiko from Sendai goes to a convenience store to buy coffee for his late wife and drinks for his deceased parents, before driving to the coastal cemetery where they lie. For the past 15 years, this ritual has marked his life since the Great East Japan Earthquake took away his family and relatives. Each visit to the gravesite allows him to share updates, such as the birth and milestones of his grandchildren, though the sorrow remains a constant part of his visits.

Toshihiko lost many members of his family, including his wife Machiko, who was 59 at the time, and his parents and brother who were all claimed by the tsunami. He survived because he was at work at a recycling company inland, but the circumstances surrounding his family's last moments remain unclear to him. He often reflects on whether things would have been different had he been home that fateful day and grapples with feelings of guilt and helplessness over his inability to save them.

Despite the overwhelming grief, Toshihiko has come to understand that dwelling on the past does not change the outcome. He treasures the memories of the life he had with his wife, particularly recalling how she always prepared his lunch before he went to work. As he continues this poignant ritual, he conveys his lasting gratitude and love for his wife, navigating life with her memory firmly in his heart, while also trying to appreciate the new joys that come with his grandchildren's milestones.
