Lot of comments on this. Why should we lie to Naomi?
Azraesha attacked the MC thinking that he had kidnapped her to this house and was essentially hostile and guarded until she understood what was going on.
The MC was, fortunately, immune to magical attack.
Naomi is likely to have a similar reaction, thinking that she has been kidnapped and similarly respond but physically. There is no reason to believe that the MC is immune to physical attack.
Keeping knowledge of the situation from Naomi until it can be reasonably certain that she won't attack seems prudent.
Or you can just read race into anything. Is Naomi black? Is she tanned? Does it matter?
Ok, I said I would let this go, and I am NOT trying to start anything. But just because you asked and I DO want to clarify some things.
My issue is that Rae shows appreciation for honesty (by giving intimacy points), yes she attacked MC right off the bat, but at least she apologized for that. She apologized for douting him telling the truth. MC has the option to be honest with Naomi, but Rae shuts him down and he just folds. What does "She looks like a commoner" even mean? Does MC look like a commoner? Later when Naomi says she figured it all out, Rae questions her about why she didn't tell them she knew. And never says she was wrong for that choice. Naomi is also the only one Rae decided to lie too. (Although, she was the first to arrive.)
As for Naomi questions
"Is she black?"
Maybe I am just wrong but later she says "my skin is Black."
"Is she tan?"
She very well may be. And that removes the race question, (if only for convenience).
"Does it matter?"
Nothing matters, when you are playing a porn game just for the sex.
If you are trying to get into the story. Racial inequality always matters. (But again there may not be any thing racial about it, that was just what I perceived, maybe no one else did.)
Now I just rolled my eyes and play the game because I like the sex scenes. (But I have a slight distrust, or angst with Rae now. And can't find affection for her) this is just my problem.
