I see this as a win-win situation. And KC Bis is having her worst nightmare possible
Would it really be Bismarck's worst nightmare, though? I mean, if KC Ark is now interested in AL Ark then that would mean she no longer has to worry about KC Ark chasing her all the time.
That is unless Bismarck has feelings for Ark Royal and wants her all to herself...
This pairing fits like a glove for some reason. Their designs and colours fit well enough with each other that I could look at it easily enough as a non-shipgirl-selfcest yuri pairing. Another pairing that I find matches well is AL Enterprise x KC Hornet, because it looks like an office workplace romance with Enty as a serious boss and Hornet as a flirty OL/secretary.
