I think a Rinha route would split the timeline before Kuroi has the chance to recruit her or he's taking the chance but we stand in his way. However, Rinha is already broken by this point and looks the way she does. We know that Rinha was in Hatsuboshi a bit, but I initially assumed otherwise because I thought Temari was just slow on the news to the point where she found out late (she would absolutely do that she is a retarded baby), but of course Rinha does have an official class designation.
