Well, that was a pretty fun read.
A few things to note:
1. The romance is super slow burn without any "official" romantic relationship being formed for either of the two MCs. So if you're after smooches, you'll want to look elsewhere.
2. There is no romantic interest between the twin MCs. (Twincest isn't my thing, but to each their own. If that's what you're hoping for, this isn't the story for you.)
3. There is some gratuitous boobage.
4. Butt-kicking happens pleasantly frequently.
5. While the gender stereotyping is rather nauseating, soldier on! Bringing the severe binary of that world into question is part of the story's whole premise!
Overall, I would recommend it. Easy to binge read in a day, the art is nice, and the characters are enjoyable.
