When my mother passed away, I even wanted to eat her bones

The protagonist of the film, Satoshi, has been frail and sick since he was a child and loves to cry. His strong mother is always by his side, caring for and helping him. Mother and child are each other's closest support. Two years ago, his mother was suddenly diagnosed with cancer. The words he once used to comfort Wu Shi were now said to his mother by him. He vowed to help his mother and made many attempts for her. He also met his considerate girlfriend Mari. Even though Wu Shi always accompanied his mother and fought against cancer with her, his mother still passed away in the spring of 2012. One year after his mother's death, his father and brothers started a new life, but Wu Shi suddenly received a gift from his mother. As Satoru wrote at the end of the film, "The death of a parent has the power to change the lives of children, and my death will also help you move forward." Facing death, a necessary issue in life, the protagonist finally gained growth and said goodbye to his mother with relief.
