u better start reading Koushaku Reijou no Tashinami if u haven't yet I just looooovegbhcbhbs how the girl was like fvck him and went to do her own thang and became a very important person in society while he sat the looking even more of a whorthless brainless piece of shit ugh I love this manga I hope more chapters r coming soon

Absolutely loathed Koushaku. I found the main character boring and clichéd. Acting like the victim when she's the bully. For one, she never explains why those who oppose classism are so evil and bad while those who support it are SOOOOOOOOOO much better. For two, she complains about those who bullied her but then gets in a snit when those who bullied the heroine used this MC's name to do so under the SAME vile type of classism SHE supports. Hypocrite much?
She never cared about the prince when she regained her memories so of COURSE she's going to be willing and able to kick him to the curb. No strength, mental or physical, required. Weakest of all types of these characters I've encountered so far.
Ktbn dfba.

You gotta understand the situation she was in. Her mentality is completely different than ours, even after she regained her previous memories, because the common sense in that time is simply different. For you classism is the epitome of evil, but to them it's normal, it's the order of life and if it suddenly disappeared, chaos would break our.
I don't know how much you've read, but pretty much every one of your points gets explained in the manga, and I didn't even read the novel. Just imagine this: you are deeply in love with your fiancee, when suddenly some girl appears and starts monopolising your fiancee's attention, even though she is way below your status (let's say you were raised with strict rules about statuses) and you know that if this continues, you will loose the love of your life and you and your family will be disgraced. Will you just step aside and say "yes, go ahead, ruin my life"? If your answer is yes, I have nothing else to say to you.
On another point, of course she will be pissed if someone used her name to do bad things and completely ruined her reputation, especially since unlike the other bullies, she did this to protect herself and her love.
I have to disagree about your opinion that the mc is weak. Even in the current chapters it is mentioned, how much she loved the prince and how badly the situation affected her, and yet she had the strength to gather enough self-respect and dignity to stand up, walk away and close this part of her life after she was publicly humiliated, her heart broke and she was literally pushed into the dirt by her own brother.
And about your last comment. Excuse me, but why the fuck would she empathize with a homewrecker who almost destroyed her life?? Try to imagine yourself in her place for a minute.
I usually love these kind of time-travel/fix-it stories, and I thought I found a gem, but thank god I read the comments before giving it a go. I refuse to read shit where the girl ends up with the guy who caused her the trauma and is still abuse towards her in the new timeline. Just, wtf?? Girl, you have a brain, use it! If your guy so much as threatens you once, you pack your bags and get the hell out of there.
This gives me major flashbacks to Nana, where the mc like the complete sheep that she is, gave up the love of her life because she was too stupid to use protection and thought that the kid MIGHT be her former guys kid and her current bf MIGHT not be able to support a child. She even threw a pityparty for herself after she hurt HERSELF and left with no word to her current bf. Her acting like a complete masochistic sheep with no backbone and no care for the others (her ex didn't want the trouble, he was forced to "take responsibility", and her current bf didn't want her to leave) made me stop watching it that instant. And judging by the comments here, the mc here is the same brainless sheep as nana, so I'm not even gonna start reading this shit.
