Why do people complain about ships all the time? Jesus christ they're fucking fictional characters.
It's simply a case of people being unable to fathom or tolerate things, that don't agree to their tastes or opinions. That said, usually not a good idea to say that or tell them it doesn't matter, since that usually exasperates the situation.
As for this ship, didn't know it existed until now.
In terms of aesthetics, they make a cute couple. It's like if you ship an angel dressed in white and a demon dressed in black. They just *look good* together.
