Mhm. Lots of things are used to skirt by it that just ruins dialogue, but that's just the most common. I've even run into a couple where they use "best friend" as a replacement. Didn't think anything of it til
But...! [MC] we're best friends, our love is forbidden!
Immediately confused (Especially when the MC and "best friend" look nothing alike) and then it clicked.
You can usually tell when they're using their relation seemingly unnecessarily in responses to people.
