It was when you saw Suna, Akagi, and Omimi watching Kita clean the boy's restroom in concern. You also saw the situation, feeling awkward about seeing the urinals and stuff. Shaking your head, you nudge Omimi and tell him that if he or the others need to use the bathroom, they can go to the female room. It was barely used anyway. So it was tidy and clean all the time. Omimi: Wait, seriously? That'd be kinda weird though y'know...? it was evident with his blush that he was off guard.
