In the summer of 2014, Daisuke, a young man from Kyushu chasing dreams of urban prosperity, heads to Tokyo in search of a richer life despite his poverty. Unfamiliar with how to survive in the big city, he ends up living with his only relative—his aunt Yurie—in Setagaya. Moved by his innocent nature, Aunt Yurie warmly welcomes and embraces him, while her husband, Uncle, remains cold and distant toward his presence. Amid this stark contrast in family attitudes, Daisuke begins his life in Tokyo, the city of dreams. The story unfolds through his struggles, evolving family dynamics, and the emotional growth he experiences along the way.
