My guess is that either the terror he felt in the moment somehow activated his OP hero powers causing his stick attack to be fatal, or it’s a misunderstanding and a monster killed his father and for some reason he’s misremembering it
Interesting, it’s been a while since I’ve re-read the previous chapters so I could be wrong, but I read it more as Eito always had feelings for him but hid them because they’re both guys.
