Lady Knight and the Duchess.
One of my fav aph pairings, why do I like it even more gen-flipped.
Actually I like any pairing where Gilbert tops (yes that includes Ivan), except man!Hungary and sadist mode Roderich.
Speaking of which when am I ever drawing my top otp IggySpain orz.....
Strike me inspiration!
