One day after practice the Fukurodani boys (besides bokuto) are trying to get Akaashi to admit he likes Bokuto. Akaashi hasn't quite come to terms with it yet, so he denies it. Then when asked "What if you met a female Bokuto? You wouldn't be slightly interested?" Akaashi gives in (mostly to shut them up) and agrees that he would be interested in a female Bokuto if there ever happened to be one. Heres where y/n comes in, as Kita's twin sister
