After stripping Miaka down to her undergarments, Nuriko takes off his outerclothes as well, making Miaka remember that Nuriko is a man. This makes her nervous and Nuriko notices this. He comes up to her (very very close) and says something along the lines of "Maybe I should go straight so I can go after girls..." This makes Miaka blush, but apparently, Nuriko was just joking (or so it seems).
