Konkon and Mikitty have always been a good team, imo.
Even though their personalities contrast each other so strongly, they seem to have a mutual respect for each other.
Since they were together in Country Musume as well as Gatas, Miki's probably worked more with Konno than she has with any of the other Musumes.
I'm reminded of this:

Sometimes Miki gets a little freaked out at being touched.
After seeing Miki get kind of freaked out at Rika's touching, Konkon knows what's up.
