Turning to Mika would be a possibility, however he knows that he isn't especially fond of them. Then again, both Zero and Yuuki have proven themselves to Mika (and Yuu) that they are far from, even the opposites, to what the other two are accustomed in their world.

But I do know and understand what you mean.
