Wasn't he going to tell her he's both the scary brute Kei and the cooking crossdresser Kei? You'd think this would be the best opportunity, seeing how they are alone with neither able to go anywhere for the time being.

It's pretty pitiful if Mayu, the androphobic, needs to be the one to start a conversation here because Kei doesn't have the guts for it. But on the other hand in this story Mayu is the one trying the hardest, Kei being only the second.
It looks like Mayu is slowly getting over her androphobia, (by dating Yuuki, of all people!) Meanwhile, Kei is becoming more shy and maiden-like by the day. Irony!
