DNF at 20%.
I really tried but I hated the bad girl character, she's bitter and condescending even when she is supposedly being appreciative of her love interest, and treats women like one of those toxic hypermasculinity men, i.e. she's cocky, egotistical, entitled, and patronizing, and she objectifies women sexually, even as she thinks herself superior. And worst of all, it is implied that she treats those women that way because they are feminine ("princesses") and she's butch.
(I don't dislike butch lesbian characters for their presentation, but I have come to realize that what really puts me off in works of fiction with a butch/femme dynamic is entirely that the butch character is written with all those problems of toxic masculinity and disrespect towards women and toward their love interest specifically.)
The "princess" character looks like a device to insult women as she keeps shaming herself for "being a slut", and wanting to be "a bad girl" but not having the guts to do anything "naughty", which is then used as ammunition by the bad girl character to mock her and be condescending, which the book seems to pass off as flirtation ¯\_(ツ)_/¯.
