well its up to the player what he want to call the girls.
I only see 2 LI, where only 1 is confirmed if u want while the other is more open and not a closed deal.
I think its good that we can not pick whatever, this is not a harem-game its about depravity, humiliation, dominance, submission etc. even with the LI its not just something vanilla, theres doors that can be open with both of them. it all depends if the DEV want it or he want to have some normalcy. with Mina theres no limits here, I mean, it can be really dirty, if the MC want to push her into that direction if we follow the narrative. with Hana Im not 100% sure how much u can push her, she will push back, maybe it depends how close the MC gets. some girls gets submissive if they accept the male and allow almost anything.
my "hope" is that I can start corruption them. as I posted before, not into any carnation-events, but private settings.
