Akira's ears drooped down. He really didn't know how to explain it because he had not clue what it meant himself. Since Roku was not a housewife it was very much possible that he also didn't know. Would Roku really want to teach Akira that the 'me'-part that he is so curious about meant doing naughty stuff? Akira was thinking who else he could ask, but he didn't know any housewives that would help him explain it to Roku.
