It expresses her real feelings towards her three-year-old son, and serves as a song of encouragement for parents all over the country who are struggling to raise their children. In preparation for her biggest solo concert at Zepp Fukuoka on Friday, December 19th of the same year, she will put her true feelings into these four consecutive songs, and will use music to tell the story of her journey to the dream stage of Zepp Fukuoka.
