Z: There we go, that’s it! My first name is indeed Justin! Congratulations, the long guessing game is over. I was so baffled because Justin would be one of the first names I come up with when I think of names starting with “J”. But then again, of course I would since it is literally my own name. I also thought that name was pretty common as well, so I expected you to guess it sooner. I thought wrong obviously.
With no restrictions basically on letters, I’ll guess your middle name as “Trevor”.
