This season should've been focused on the kids because S1 was like 95% the parents and 5% the kids. But no Lee Jungha means it's prolly still focused on the parents :/
It's interesting. I dont think the fantastical element is real tbh feels more like symbolism. Jane doesn't have literal dark wings , I think it's somehow setting up his background as a fallen angel who had something happen to him in the past that turned him manipulative.
