First of all, she's not a character who's willingly marrying with the "villainess" role in a silly/funny way like some other isekai stories. She's indeed being targeted in that way, but she's not forcing herself to act like the villainess, she just seems to be walking towards that direction without pretenses or worries, maybe blindly (as if that world wasn't dangerous for her, except for that possible forced baby), which ofc it's pretty questionable and strange, since it seems she's not aware of the real risk she's in.
So far we don't know why she doesn't care about things that can put her in danger or why she's walking towards that path without concern, why everything seems so hard yet easy for her, but I guess it contributes to the contradiction of that new world, the sky god and it adds point to the misterious vibe and funny side of the story. It also feels like it adds some balance to the dark side of some characters and the numb situation of others, it's like she's in the middle (her personality really helps to showcase other characters's issues as well which I think it's peculiar, I'll have to wait to see how this develops in the future).
A part of me feels like the author is making a big BIG sour joke and criticism about everything, this manga is like 1k of lemon with 1k of sugar (I didn't expect it, but I'm happy we're getting some hints towards that direction). If u read it, you'll have fun, u can get mad and you'll probably even get a surprised face thinking "wtf is happening" and I love it! There's many layers in this story to discuss about.
I even think the manga's title can be a little misleading (like in a joke)? I mean, she's just having fun and getting stressed by her horrible future, while around her, it's happening some crazy and dark sh*t. It's really funny to see all this haha.
While she just does whatever she wants, without thinking much (which it's been annoying for some haha) and is just enjoying what she can while trying to pursue her goal, she's also getting hints there and there. That's why I call her silly but not that silly, and i think that's what's bringing some mixed opinions about her character and actions (so far, I don't mind, I hope the author won't dissapoint 🤞🏼).
For the people who're willing to find a powerful, cunning villainess, who wins over everyone in 2 seconds well, I think probably you won't find that. But she's still likeable, she's a mixture between honest silliness, naivety, and there's a hint of darkness in her character as well.
For the person who said she's acting like she haven't read books in her past life I agree, I just wonder if this was her first novel or what. If that's the case, I don't blame her for her actions, since she didn't finish the story, there's really no point for her in getting against anyone per se, but she should have more awareness because she doesn't know much about the future after all.🤷🏻♀️
