Why almost everyone in this fandom ship narumitsu(phoenix x edgeworth)? Where that ship come from?

When i'm first played and entered this game fandom, i'm shocked when i saw a narumitsu ship. At first, i thought that ship was a joke ship because gay ship like that always get protraed like a joke at game i played before. But i was wrong, people are serious about that ship and i was confused about that. Where this ship come from and why almost everyone in this fandom ship narumitsu at first place?
