That's a crazy amount of words and assumptions just to justify her literally enslaving this guy to be her "closet" with the threat of magically ruining his life with a false rape accusation. Seriously, dude, it's fine if you like the scenario, but it's actually unhinged to claim that it's morally incorrect to dislike her.
I feel like what she did goes quite a few steps beyond "tsundere" territory and literally into sexual assault, false accusation and actual enslavement territory. There's not even a hint of consent in this story. It's also absolutely wild that you claim that "women would know more about blackmail than men" as if men arent the main target of false accusations to begin with. Yeah, maybe they know more about doing the blackmailing /jk. I've had personal experience with the kind of damage that women can do to a man with just a few words, so I would appreciate it if you wouldnt make such wildly unfair, sexist assumptions.
Please point me to the passage where she clearly states that she wont use that blackmail scenario in chapter 2? Did I miss it? Literally, go to page 11 in chapter 2 and she threatens him with that exact scenario. Her saying "but really there is no threat to you, I just want you to do your best" is completely inconsequential, because she continues to force him to do things later. It's hardly a clear message of "you're free to go if you want to." If I was in his position and knew that she literally had the power to ruin my life and that she was essentially telling me "I'm your master and you must be at my beck and call all day," I would still feel insanely uncomfortable about that dynamic, even if she said "OBEY ME, but there is no threat to you I pinky promise teehee."

That threat that she made was very, very real. She even made him go through the consequences, of having the police talk to him, of being close to have his life ruined, before reverting it. That's not something you can just skip over. That's not something that can be glossed over with "teehee be my slave, but you know I just want you to do your best, there is no threat, I swear! But if you disobey..." She literally made him live through it, then threatened him with it, while saying "but no really, I swear there is no threat against you, just do your best being my slave lol." Sorry, but that just doesnt cut it, not even close. Even if she acted like an angel after doing that, profusely apologizing and trying to mend things, I would still view that action alone as a dealbreaker for any romance. She doesnt even come close to doing that, but instead enslaves and humiliates him.
Ugh.
If she is as good as you say, does she ever give him a clear choice to leave? To stop being her "closet"? Or does he still have no choice? How exactly can we gloss over her false accusation threat if it is clearly still being used and if she is clearly forcing him to obey her? Even far after chapter 2, she still claims that he has "no choice and must obey her" repeatedly. That's coming from someone that he knows can ruin his life at a whim. Just think about it for a bit.
That last passage of yours seemed so defensive about women, so I'm a bit a curious, are you a woman? That would explain a few things about your assumptions, I guess, especially the dismissal of her false rape accusation threat that she is holding over him. (Not to say that all women think like this, but it's more likely that a woman would think it is no big deal I guess, from personal experience).
Either way, your staunch and unfair defense of her just makes me dislike her even more, because it reminds me that there are plenty of people that justify shit like this... Sorry, I guess I just really hate this character. Maybe it's just personal and I hate women like this, but I feel like it's not just me and likely most men would agree. She is obviously not real and larger than life, but women being manipulative predators and blackmailing with false accusations is definitely real. I know that all too well.
This chapter was just a reminder of that. How she pinched his face and told him that his "duty is just to be her closet." The dynamic is just the same as always, just more extreme. It tells me that if he would ever choose to leave and not return her advances, she would just use her cheat ability to force him to stay as her slave, if nothing more. That's how she lives, isnt it? By getting what she wants with her "redos." Again, ugh.
