Arashi wo Yobu Otoko

Arashi, the eldest son of the Nakajima family had lived a life chased by debt collectors due to his father, who became in debt because he was a guarantor for someone. One day, the debt collectors was causing nuisance again when a foreigner, Steven appeared out of nowhere and helped Arashi out.
He brought the breaking news that Arashi is the grandson of a conglomerate's chairman. Furthermore, Steven claimed that he's Arashi's butler. And so begins a high tension comedy between the super butler and the former-plebeian master!
