IRONY: If you would have bothered to look at said posts you would have noticed that those people decided to "disagree" with me by trying to make my viewpoint seem wrong when I specifically mentioned that my viewpoint is based on my beliefs and character. This is basically what you are trying to do now, hence the word irony in regards to your statement of "Have a little self awareness". You could not be more idiotic and at the same time prove my point.
CUCK: If you decide to help someone that is on you and you alone! You shouldn't expect anything in return(praiseworthy). If someone is disrespectful, arrogant, and invalidates your every opinion and you still put up with it(doormat and a wimp). FFS, not so hard to understand. This is where the cuck element comes into play but I'll elaborate later on so bear with me.
DELUSIONAL: This is will likely be the only time I will use the word "wrong" as in "You are wrong!" because my "held accountable" statement was made in regards to her overall behavior, not her direct relationship with the MC.
Let's use your first chapter but turn off the cuck vision for a moment, you said the MC's memories of her were "damn she’s rude and idk why people like her". I actually went back to said chapter and you somehow failed to mention the fact that when asked out by a random character her reaction was "who the f*** are you?". It is mentioned that she had a lot of "friends" but you can also tell a little that those said friends are only people she deems worthy of her precious time or fans of her popularity that cater to her ego. He also remembers what she was called during that time by everyone in school which is "The Arrogant Bitch"(she was actually called The Arrogant Queen but bitch has the same meaning in this context and I think it fits her better). They actually skipped a few elements that make her seem worse in the light novel but I'll only stick to the matter at hand. Bear in mind, this was all before she dated Mike Tyson so the "abused" excuse doesn't stand. Basically, you see a nice girl, I don't.
At the top of my head, things that she could answer to are why was she a bitch to everyone not part of her little group? Why did she have a lousy relationship with her family? Why did she not try to get a job first or go to a woman's shelter? If she had so many friends why did she not ask for help from them? Why did she decide to move in with a guy she barely knew?
PSYCHOLOGY EXPERT: This isn't directly for you but to cucks in general. I'm willing to bet my left nut that if the FMC was ugly or if the artist wasn't so good this shit would have never gained such popularity.
In regards to your view on FMC and how she behaves I don't have much to add. You have a your view on the matter and think being abused justifies treating other people like shit. I just don't share the same sentiment but I do respect your opinion. You can't tell what trauma might do to a person and that brings me to my main point of your statement and why I used Psychology Expert.
I've seen most of you cucks bring up abuse and even real life abuse in the discussion so I'll make this perfectly clear for you on each front. In regards to the manga, the MC's so called "therapy" works because the author wants it to work. The whole point of the story is to give a cuck the idea that if he is a doormat for long enough and caters to the whims of a bitch she will eventually turn into this beautifull princess that will adore him. This has been proven to sell and/or attract attention and as the saying goes "any publicity is good publicity".
In regards to real life trauma and/or abuse: You pathetic wankstains need to stay away from any person that you know has went through shit. This also applies to the glorious me and any other person reading this. I don't mean this as in abandon them, I mean this in the sense of being their healing engine. If you care about someone that went through something traumatic your only job is to convince them to get professional help, you can be there for them on the side if you wish to. None of you opinionated morons have ever touched a psychology book and even if you have it's never a good idea to treat someone you're close to(and I don't just mean romantically). There is a reason therapists aren't allowed to date their patients.
THE HERO: I was going to end this with "CUCK 2.0" but Holy Shit! THIS is why you people get called cucks, it doesn't have to be something in regards to a woman for someone to tell you're a cuck. You and others like you always go for the speech that tries to sound empathic and humble yet somehow always have an excuse. If you want to be a better person be a better person. It doesn't mean you have to do something grand and it doesn't have to always involve a woman for your "thirsty needs". Help an old woman with her bags, get a cat out of tree, pick up litter and put it in the trash, buy a random kid in a store a treat(while other adults are around). There are limitless nice things you can do if you want to be a better person, you don't always have to be the hero. I have more flaws than there are isekai mangas out there but at least I own up to them. Every time someone is called out for being a cuck they make it like it's the end of the world. Whether you let it be your whole identity or a part of who you are is up to you.
CUCK 2.0: Hey! I did get to use CUCK 2.0 in the end. Well... doesn't really fit all the way though. Anyway, I guess there is some cuckiness in you assesment but again, read my previous statements. It's ok to help someone, but going above and beyond for someone that's a bitch... I don't really agree he's doing the right thing. Yeah, well, you know, that's just, like, your opinion, man.
