Bug, a college graduate who is full of yearning for society, lost her sense of direction after her love was frustrated. She was adopted since she was a child, and she has always longed for a home of her own. This is just a small ideal, but she has not had time to realize it. She has always faced life with optimism, but she doesn't know that God has played a joke on her. When she walks into another time and space, will she continue her little dream and live to integrate herself into this world that does not belong to her originally?
