Hi Bootie-Pup,
This is not based on the novel Maid for Me. This is an original English visual novel with it's own storyline and characters. We weren't even aware there's a novel called Maid for Me.
No worries! It's what actually initially brought me to look at the game! It's a lovely idea and look forward to purchasing a pre-order when I can!
Thank you for your support in advance!
