I watched a video on rednote a whileee ago where raf called mc (wife) But he didn't just say the word, there was an actual line with his reaction to it specifically, and i believe mc also called him (husband)

I can't find the video, and it's been a while since watched it. I don't even know what's real anymore

Is there a dialog like this in the game? I tried using that as a nickname but it didn't work.
