@Yuki - Like I said, Kei said too much in that instance, but during the other times, they even out quite well. That is precisely the reason Kei felt guilty when she insulted Kusuda about the gloves. It is not like their usual exchanges.

In your 2nd to the last post, you seem to make Kei the bad guy (girl), and she was, but only for this episode. The rest of the time, she and Kusuda are just verbally jousting as always. She isn't taking advantage of him or anything.

If Kusuda had said what he usually says to Kei to some other girl, he will probably get slapped. Is he then taking advantage of Kei's lenience?
