Truck that hit kiritaka

Do you guys think that there’s gonna be a reveal about the truck that hit kiritaka. Like maybe oyaka’s mom knew what they were doing that night and specifically sent someone to run over him so oyaka would stop being so obsessed with him? We already know she hated kiritaka from the beginning and it seems like the author is setting up oyaka’s mom as possibly being more sinister and manipulative than oyaka (or at least showing where he gets it from)
