How do you view Nezha and Ao Bing? Brothers? Best friends? Or do you ship them? (Nezha 2)

By what I've seen, I personally view them as best friends or brothers.

With there sibling-like dynamic, and how the demon orb and spirit orb were originally the primital pearl (I probably wrote that incorrectly).

So, what do you guys think of these two? Brothers? Best Friends? Do you ship them?
