Hatsune calling Haku Master?
All due respects I thought it was like the other way around since Haku is the fake, I mean I love Haku and all but I'm just saying.

Thanks for the translations its appreciated.

No. Caffein the artist often uses Haku to represent himself when depicting interactions with Miku. So in this case, Haku = Caffein = master.
