He then enters a consumer finance company which is actually in the illegal loansharking business and tries to get out of his financial problems while being tempted by the power of money. At the same time, he is caught in a love triangle with his ex-fiancee played by Kimura Fumino and his mentor's daughter played by Oshima Yuko. Watabe Atsuro plays the owner of the consumer finance company while Kis-My-Ft2's Tamamori Yuta plays Kusanagi's younger brother.
