So, can I just say? I like your username. HOWEVER, because my brain is weird, I always read it as miss sir king (bcs rey is king in spanish), so it looks like a long line of honorifics. I think it's hilarious. Don't know if you intended for it to happen, but I adore it.
That is actually very close! So, on AO3 it’s MsSirEy, and better shows each of the parts, but it is indeed meant to be Ms. Sir. and then Ey, which is part of a pronoun set that a friend of my partner uses (ey/em/eirs)! But, I do really like the idea of King being one of the parts!! Ms Sir King! I love it 🥰
