i think this was what was going on....*4 yrs of japanese class in highschool powers activate!*
Risa-I'm a college student
Ai-*looks at the camera*
Risa-*points at ai*she's really a college student and im realy highschool student.
then she says something with yaku? idk
it was too mumbled but thats what caused ai to look away XDDD and then risa just says she's just fooling with her
hoped that helped a tiny bit^^; and i think they were doing a play or something? idk
