I don't know why people are shipping those two. There not even in the same universe or company for that matter. Unless someone made a fanfiction for this. I could care less for frozen anyhow
Yes, most of the fandom knows that this isn't a cannon yet. Or ever. Disney knows. But to be truthful, I ship this two because I could see their chemistry, and would make a fairly good couple, considering their pasts, and would understand each other.
