[Yokuutsu]

Vivi would hit Riyo (lightly of course) is he knew what the other is thinking. "We can do the blood test this time...and we might have to do it again depending on the result of course....but first." He points to a door. "There's the bathroom." Oh...look....Vivi just disappeared. And everyone in the area can hear the relieved sound he makes as he pees. It's the best pee of his life so far. When he comes out, "And now for the blood test." He takes them to a different room for this. And a nurse takes Vivi's blood and all. "Same as last time, make an appointment with the receptionist...and we'll call with the results soon."
