Yotsuha's mother maybe????? Is that why the grandmother's reaction to Yotsuha was indifferent? Wonder what Yotsuha's family had to do with Rei's (unless- it could also be Fuu's father since he was a scientist, although cmiw he died when Fuu was still a kid tho not exactly sure)
Wait wait... letters?
We know that Yotsuha exchanged letters/was penpals with Fuu and Uichi, makes me wonder if she wrote her brother too. But why would Rei kys just from knowing that knowledge (if it was someone from the future or her brother if she wrote to him)?
Hope we get to see what...
Imagine if they're feeding human meat to hirono-san (? I forgot if that's her name lmao) i watch too many horror games smh
What's th title of the novel ?
