so my guess is that they are all just faked family members dressed up the same? the reason why the dad is so scared is because the mc is actually just murdering the actors
that's what i also thought bro. they are not immortals, they just changed 'actors' that look alike or he himself is delusional(like that) i started to doubt that he is in drugs from what the former singer said.
For real this student teacher can catch these hands... that said i hope doojoon shows up as her boyfriend and everyone's gonna shut the fuck up bcs wht are you gonna do? Fire the gf of the foundation's ceo, whose also pregnant w his child?
here are the raws btw
