The father chose to stay by his wife's side, leaving a young Yuichi to wait all alone. Just before his wife drew her last breath, her final words to him were── "I want Yuichi to live his life with a smile." "When that boy wants to cry, please let him cry properly." But the father, on the verge of being crushed by his own grief, couldn't keep that promise. By forcing himself to keep smiling, thinking "I'm his father, I can't cry," he made Yuichi believe that he, too, "must not cry." The father has been blaming himself for years. Yuichi doesn't know this.
