About the thing with Sori being a stone top and Iseul being a pillow princess... I support it wholeheartedly and I actually rlly like pillow princesses, though I do think that a lot of these gl manhwas are trying to enforce traditional gender roles into their relationships or trying to follow a bl type blueprint of top/bottom roles when they could actually be doing it differently, in a way that actually accounts for women's bodies since they're different from men's so sex will also look pretty different. I think a good example of "top/bottom" in wlw context would be in something like "More than my friend's sister, something else" which you can see in in ch 8, in Sadistic beauty sidestory, and The third party. I actually really like that kind of dynamic and hope we can see it more.
