（￣へ￣）did i see that shit right?

I'd say ignore those chapters if you can. I didn't read it all but I think it's more like a sort of borderline dubious con BDSM role play... Anyway, after I saw the other one with a flea-sized Seth I realized the author was probably just messing around with the readers a bit, in order unwind (and given the long ass break they took, you could tell they really needed some unwinding).

And have you seen any consensual sex in this manhwa?

The only reason I’m not irked by it is because it’s not canon and it’s an AU type thing. The extra chapters just make me want to see Horus’s face even more. ;-;
