Forget about other characters: Rae is the best. The scene in which seduces the salesgirl is both sexy and funny.
I agree, I expected more from her second visit to the store.
But considering that she's upset because of her armband, I understand why it wasn't.
Actually, the other characters should be in the house to be amicably "corrupted" by Rae for the amusement of herself and the MC. This game would benefit from more kinky and fetishes and more uninhibited characters now that they know well each other in the house and are mostly great friends. The house is boring like it is.
For example, a character could develop the fetish of "exhibitionist" and the MC could enter casually in a room and instead of see a character watching TV or having breakfast (boring at this point), see her flashing other characters. Or other characters could develop submissive/masochist and dominant/sadist tendencies (that are hinted now in some characters, but not fully developed) so the MC could casually enter in a room and see a character in bondage waiting for her "mistress", and maybe have some fun too. The MC could summon a room with sexual toys to the enjoyment of all the house...
As it was written by someone above, this game is a bit different.
This is not a story of corruption and kinks, and Rae has never been and never will be the one who corrupts other characters. Here she is more of a girlfriend, mentor and guide.
All her teasing and jokes about Lyrielle and Cait took place not because she wants to corrupt them, but because, being a succubus, she feels emotions and sees the real desires of the girls.
And girls only sleep with MCs because they understand who they are and what they really want.
And personally, I would not want the game to turn into a brainless sex marathon with lustful whores and endless orgies.
My only dream is the appearance of a character for which Rae starts to be jealous.
The same beautiful and smart, but cynical and practical.
In my opinion, the dialogues between them should be very funny.
