Twisted Gambler

Kajio witnesses Nanase Dai, who goes to the same cram school as him, coming out of a pachinko parlor. He's charmed by Nanase's attitude, which is the exact opposite of the honor student he sees at school, and confesses to him without thinking. Despite being rejected, Kajio makes a bet that if he's able to get Nanase to fall for him within one month, Nanase has to go out with him – and Nanase, who loves gambling, accepts the challenge. In the final summer of their high school lives where love is wagered, what will happen to these two in one month?!
