With his step sister “Haruko” a month before marriageI went to my grandmother ‘s house to give a greeting. He dreams a strange dream after seeing the old barn there. Her brother, Haruko, was the mother of Fumiko grandmother, Sakura, who was trapped in a barn. He secretly hides and witnesses what happens to Sakura. As he wakes up, he realizes that dreams are real. I feel a strange feeling to my sister Haruko. And, it seems to mix with Haruko who seems to have dreamed the same dream.
