This might be wrong, but I hope the maid and the girl don't get together.
Because, if she's scared of boys, and she if she shows any romantic interest it will be to the girl that the boy is pretending to be. But, I don't put it past the creator to just suddenly go, "Oh, she likes girls, but she's suddenly okay with boys."
If that is the case, then why wasn't this manga just a Yuri?
Seriously, that trope is freaking annoying, and I can already guess that's here this manga is going.
But, I admit, I might be wrong. However, how often I see this happen, it probably will be the outcome.
