Soooo.. In Indonesia we have something called 'SANTET' basically when DUKUN (aka Shaman) put some harmful spiritual figure to someone else and it could cause some pretty bad thing (even lead to death).
One of my friend believe her late mom got santet because she vomited actual fucking HAIR and NAIL (for hammer one not finger).
Idk Korea have something like this cause I never seen their media about sending bad spiritual figure to someone else. But this manhwa gimme that vibe
