I'll presume you demand an explanation my good man, so I don't plan to disappoint. The way you come across each other is telling:
-Yakuu brings you to Malka's house and we already see that Malka is a somewhat unkempt sorry, undead dragon. She's living in a mansion in the middle of the forest with strange, horrifying undead servants, all who speak obtuse and strange things. All of this makes her come across as one note, just another terrifying giantess of Homaspernia, only she leans more into the warrior with a code thing that is subtly implied by Yakuu. Again, she treats us like a slave and only seems to respect strength for strength's sake. She wants to make the MC stronger to play with him, and she doesn't seem to truly come across as interested in him beyond as a plaything.
-By contrast, in the earlier versions you came across Seinaru by running from Naya with potentially broken ribs before encountering her in a cave. She is immediatly standoff ish and tsundere. She can kill you if you lie out of fear, but she can also bring you deeper into the cave in her arms if you're hurt. Her relationship with Haramunia does a great job in humanizing her, from how this nice cat-girl cares about her well-being and living in isolation, to Seinaru catching herself when mentioning dealing with a bunch of thieves murderously, to hugging by the river together, etc. Then there are the subtle hints she grows to care for the MC even if she isn't that impressed by his weakness. Letting him stay in her lap, letting him keep a knife used for cutting an apple, etc. Hells, she's actually somewhat understanding if he's horrified by the blood left behind after she slaughters a couple of thieves. At some point it becomes clear she can come and care for the MC despite saying she's fine and doesn't need anyone, and she plans to train him to become stronger so he can stay alive as her 'treasure'.
