Arashi members Ninomiya Kazunari and Sakurai Sho star in this comedy series based on "Yamada Taro Monogatari" by mangaka Ai Morinaga. Ninomiya plays the title character, Taro Yamada, whose family lives in extreme poverty. But because of his looks, intelligence, and athleticism, others mistakenly believe that Taro comes from a prosperous family. In contrast, Sakurai plays Taro's best friend Takuya, who really is from a successful family and who often helps out Taro in various ways.
