I think they mentioned the mom was the one begging grandma for money to prolonged warded time. So she & the brothers might feel the lost. But we can just assume if it's from the guilt from seeing the accident real time since the brothers were there or it's just the feeling of lost when they had no one to rely on doing chores now lol

So every time she woke up in Korea, were the brothers feelings of regret real or not? Like it’s obvious the sad and grandma had none. Also can’t really remember the mother, besides the fake feelings she had from the star guy. I just wish I could see the actual moment when she died/the aftermath…
Also will we see the (shifters?) animal people again? There were all these bad guys in the beginning but none of them are actually important
