I got to read it even when I didn't log on to my wattpad profile (and even then, I can read it even when my age at wattpad is below 18).
Although I don't think you'd get banned for this story if you didn't rate it as 'R'--there are minors posting stories that should be censored without rating them correctly.
I'm interested about how you're going to make this into a VN--you have a lot of narration going on (since it IS from the first-person POV). Some stuff read like infodumps to me, like the stuff about Aryanne's origins, and the information about their house (it kinda struck me as weird because she was panicking about the 'spasms' Sven supposedly had, and then she's talking about the house).
Aryanne's behavior is, um, weird. I was wondering whether that's the first time she's done that, because she doesn't seem to be having enough second-thinking about what she's going to do when she's with Sven.
Overall, though, the story's premise is pretty interesting, and I'm adding it to my wattpad library because I want to find out what happens next (especially after that cliff-hanger).
I can't wait to see how the characters look like in a VN

I'm also wondering what the choices would be...
