Honestly, amongst all isekai/reincarnationn tropes, this MC is probably the darkest and most scheming. I mean I've read webtoons and mangas with female MCs who have killed many more but it's mostly that martial arts genre where killing is the norm or when it comes to scheming, it's usually a woman who gets back at her family or her cheating husband . However, for an MC who isn't physically strong not the usual scheming woman in a harem, I'm very impressed. But I also fear for the future, usually when the man is scheming to protect the woman and her position, it is swept under the rug but a "villainess" MC with a very pure ML makes me anxious. Also the fact that she keeps thinking she is unworthy of any fleeting moment of happiness adds to the overall angst.
I think heartwrenching episodes are to come in this story
