Should they

It doesn't matter what we think. AoT has ended.

I know but still

AoT has ended, therefore it can't happen canonically. In my opinion, anyone who creates non-canon shipping content should be treated like an anime hater.

Besides, there's not exactly many places you can go on a date in AoT

Lol that's true. But what about the mountains? the place near where they found mikasa Not many titans go there during an attack

Googled it and apparently Eren is dead now

That's in the manga.
The anime for AoT didn't actually end yet. There's gonna be a season 5, but the manga of Aot already finished

If they're not blood related, they're free to be dated

Yup

When I first watched the show, I said I shipped them but my friend told me they're siblings. Then a few days ago she said they're just friends so idrk I kind of ship them

If they're adopted siblings, no.

Dude if they’re siblings to any degree it’s wrong
