Wow, that was something. Honestly I didn't know what on earth was the direction of the VN but I had an idea based on the images but the entire character of Louhi is quite interesting. Kudos to his voice actor for conveying Louhi's friendly but unsettling dialogue, especially when you first meet him and his way of speaking is odd and like he's so bad at acting that it tips you off. I have to say that in some way I find Louhi interesting because of how funadmentally disconnected he is to people's emotions. You can see it reflected in the way he talks about his "patients" rebelling and getting angry at him, and especially towards MC whom he kept violating by crossing her boundaries, didn't care about her choices, and so on.
I guess you wouldn't really try and emphasize with your food in a way, Louhi's entire character was really unsettling, how he really tried to say that he cares about his patients yet doesn't realize how horrifying his actions are, that he lacks no remorse for what he's doing and in some ways lacks self-awareness because of how twisted and cruel he can be even if he disguises it as love, care, and affection.
I'm curious about the little red riding hood themes, I'm not sure you meant it but well, it can't be helped because of the setting like the dark dreary forest, the wolves, an ill grandmother, and even a man with an axe at the very end. I'm unsure if the direction of a plague monster was because of some people interpreting the story of red riding hood being sent to the forest to die or because her mother had to have her evacuated because the town had an illness around them. Aside from that, this was a rather interesting experience. I'm floored that this is a demo, like it truly felt like it was a complete VN! I'm curious what'll happen next in the direction of this story.
