I'm personally okay with either one, however there's a lot to think about for either one

Like if it's together, you gotta think of the reasoning why, and how it benefits the story you're trying to tell

And if it's another person's OC, you first gotta ask them and you both have to think about how it affects both of their stories

I'm not a big shipper in general since I have a very horrendous history dealing with R̶W̶B̶Y̶ shippers in general, so it's whatever for me. If it's for a story, then baller. If a friend (operative word here) wants to do it, I'll see how I can work around it.

But yeah, to each their own, I guess...
