I made a comment a few days ago on why Sarah works so well as a character; the thing with Rachel is that everything that makes Sarah good is what makes her bad.
There are lines that Sarah never crosses, or instantly apologizes when she does. Sarah is never actively detrimental towards the group. Yes, she calls you an idiot; yes, she is sometimes unreasonable, but none of those things are ever particularly damaging. The one thing she does is slap you at the party, which is a) somewhat understandable, given how fast things are moving, and b)something she instantly profusely apologizes for, multiple times. Even if she didn't, that's nto something that is going to actively mess with your life in any way.
Compare that with Rachel, the other tsundere wannabe, and you can see the difference. Rachel has just been an annoyance so far. Like, if she had just stuck to being a feminist stereotype that just screams rape at everything that moves that'd have been kind of funny, maybe even memorable, once she turned intro a proper LI. But no. She actively tries to get the MC into trouble at every single turn, often legitimately interfering with his life, sneaks into his home to take a picture of Hannah she had no right to take, and then comes back demanding BS. Chances are she is also the one that stole the book. So far I haven't seen an ounce of regret or guilt for her actions - nor does she even seem to understand what she did wrong.
All of this is to say that Rachel has one hell of a battle to fight if she wants to convince the MC, and consequently the players, that there is a reason not to skip every scene she is involved in the future. Though the author has been good at keeping the line between cozy and having some drama or more serious stuff, so I do have some amount of confidence he can pull it off
