I'll judge this on the genius. 8 manhwa chapters in and her personality is the most unique aspect, but the genius element is very soft and handwavy as needed.
MC is dorkly autistic, where it's not clear where her sarcasm begins and literalmindedness begins. Binging the novel for New Years and Kiana is more entertaining than (closest comparison) Deborah from Isn't A Wicked Woman Much Better?, like a lot more heartfelt and believable. This is going to be a good manhwa adaptation.
The characters really carry this hard. So much so that this is one of my favorite reads in this particular genre ("villainess" regression). The whole family is dysfunctional in a fantastic way, and I can't wait to read more of this. I absolutely recommend this. I also think the 8/10 this currently is rated at is a fair one.
