After finishing the novel I can say that she is a 'bad' person is she true evil? No but if you really look at her 'revenge' from an outsider's pov you can see some glaring points like what gave her the right to fight the true daughter etc. She is neither good nor bad, the only thing to keep in mind is her 'reputation' something she cares about. She's a really good villain MC!
Right!! This girl had her head chopped off. She was a brat before, coming back. It makes no sense to me when villans get reincarnated and all of a sudden they have a heart of gold. Like you cant change who you are so easily. But my girl aria gonna fake it till she makes it. And lets be honest most of us would react the same way she does. After everything she has been through, she has trust issues and wants whats best for her. But if I was her, I probably wouldnt be as smart as her as she plans every single move. I really enjoy this, as you can see her true intentions. She aint about that bs

I think the MC should be accepted for who she is: a true villainess MC who became the person we see now because she got screwed over before, and now will use any opportunity to her advantage. This means showing her in a less than noble light. This also means she will do less than ethical things, think scheming thoughts. There are already so many, many, MANY other villainess manhwa out there who has a heart of gold, who are MEANT to be liked, saving the world with her goodness and purity - at least give this manhwa credit for portraying something different. This manhwa is not common because of that, and it doesn't fall into the stereotypical tropes out there. Can't we just appreciate Aria for her schemes instead of trying to force her into another Bakarina, Elise, Penelope, and other heroines. This means not apologizing for who Aria is. She will have her revenge, and she won't whitewash things. If you don't like this setup, maybe it's time to drop the manga and read something else. /rant
