There is some weird psychological conflict here at play but it's interesting as a one shot. I'm glad it didn't escalate just for scaling the shock meter.
I'm wondering if a concept like death has an age here. Like obviously they look like obviously it looks like an adult buts it's implied to be much older. So appart from a small moment it felt much more to me like obsessive paternal love than romantic interest. I still feel some situations were creepy but I don't know why it didn't bother me as much.
Probably because worse manipulating things were already happening.
