I can't really give a huge spoiler (as I'm also bad at explaining things and english in not my first language).

But it's about myth and family matters and some taboo topics too.... Like family affair and as now we know some of the characters, one of them is part of "that" particular family.
It kinda sad at some point but also make me feel like ... "Damn old people and their stupid beliefs", and this one is regardless of the missing of the left hand. Just as i said before, you put the wedding finger in the right hand right? And it go even downhill from that....

Not like "kink" but it's about some family 'drama' they have for generations... And as i said before there's some taboo topic in that specific family ( tw // incest ) and you know that a child that born from incest is... Genetically not normal right?
I'm not gonna give the details about it but let's say since that kid born, the family have some 'custom' and it's regarding of killing and make the 'left hand' like some offering cause they believe it's the curse from someone (i mean we talking about people from centuries ago, different from how medical field is so advanced like these days).
I'm not say who is who since it's gonna ruin the "fun" it's still kinda a long way to go there. But since we've already been introduced to miss Yuzuki i think we're getting there guys (▰˘◡˘▰)
I FUCKING KNEW IT!!! Damnnn the plot thickening (and special thanks to my friends in SNS for give me a head up before it LOL LOL)
I read the novel one btw, idk but the why this plot going THERE is like the feeling when i read akiyoshi rikako's novel LOL ╮( ̄▽ ̄)╭ no wonder it caused a roar in my country's reading community haha.
I can't give a huge spoiler cause it's gonna ruin the vibe xjjsnsksns but i can say it's not just a "strange house" but a strange household LOL dbdjnsks and save your theory for this cause it's just the beginning~ (before i read the novel i have a hunch about the left hand getting cut and can't find it everywhere, cause i think it's about the hand when you put a ring wedding on it and i can say that my hunch is not wrong but not entirely right either)
