My thing with Hana is she lost all agency once she entered into a contract with Lux, he’s still a sex demon and like you said, why would she run to other sex demons for help like that was going to do anything. Like how could she not know entering ina contract with any demon would be dangerous lol. Pass showed he’s still a sex demon at the end of the day when she was crying because no one remembered her and Caligo definitely isn’t a good demon and the most obviously manipulative one but she keeps going to him for help knowing how he is.
I wonder if her first initial contract with Lux and them releasing those sex pheromones made her more susceptible and weak to sex demons over all because through out the story her body changes to be more compatible with Lux and maybe demons overall. She didn’t initially release that scent they like at least not very strongly until she kept having sex with Luc. Like without the author explicitly saying it, she’s definitely losing her soul slowly from the human world but I wonder if she’s now drawn to them now, it would explain why she’s getting more intangled with these three demons. She was so innocent in the first chapter but now she’s so used to the madness of sex demons, her character development has been really interesting to say the least.

Hana is actually such a confusing character, definitely a lot of misunderstanding with Lux—let her emotions drive rationality away due to fear, I think all of this mess could have been really avoided if both of them were just willing to communicate :| I don't remember anything now, and I think she's pretty dumb for approaching Caligo again knowing what happened before, I don't know why she did so but I assume it's something related to getting back Lux??? When she was the one who drove him away?? I'm so lost
