came here after reading the novel and found out there's a manga with even more chapters. i was so bummed about keita and the implication that the mom schemed it all, but im glad the manga said fuck you to that plot lmao
idk if you've read the novel or not so it's spoiler, but in the novel it's left ambiguous about the identity of the corpse from the second house, and the mc's friend kinda heavily insinuated that the wife's mom really did plan it all out to get revenge on the family while sacrificing keita for her plans, including even allegedly faking a letter from keita. which is such a bummer for me personally, especially since i liked keita bc if we trust the letter, he actually cared for momoya (the cursed boy is called this in the novel)
and i love every second of it. I can't look away. i want to read more. it's so bad that it's so good.
