Shingo becomes attached to the fatherless boy and eventually he decides to build a house for him and his saleswoman mother. Understandably, his wife, daughter and his apprentice are not very happy with his behavior. He seems unable to read the air around his home and business. While devoting himself to build the house, the boy's father suddenly appears, wanting to come back into his child's life.
