Representshipping = Crow Hogan X Nozomi/Mochizuki Haruka.
Haruka's rough information is here.

"Plus, I'm not even one of those Signer things. So, I'll leave it to Haruka to fill in for me."
Reasonings:
Crow told Haruka to fill in for him too in the battle against the Dark Signers, which could be assumed to mean that Haruka was representing Crow's will to support the Signers in the battle.
Haruka was the new fifth signer in Reverse of Arcadia parallel, but Crow was one in the anime parallel. In other words, they represent each other's role on respective parallel.
Crow was the one who gave Haruka her family name "Nozomi" on the Reverse of Arcadia parallel. The name represents Crow's hope for Haruka to live as she wishes.
Extra note: Actually I wanted to use Snowdropshipping as the name, but I saw a history as someone was about to claim the name in the past, so I held back from using the name. Plus, I had already used a flower language reasoning for Haruka's other ship, so I don't think it was a good thing to do the same thing again or I might have the image of naming all my OC ship based on flower language.
