I've been trolled so hard I'm not even mad. That was hilarious.
But given this author, with their near-parodic rehashes of stock plots and their chapter opener pages ripping off old album covers, and all the other stuff they pull... I'm still completely uncertain about where the hell we'll go from this, or whether there's actually going to be a second level of trolling where it turns out that the king was lying his face off in response to Sango's denial that she's actually in love with a human - but might have told her the true end of the story if she'd just been straight with him. (I find it rather unlikely that if the king's being honest about falling in love with a mermaid, he'd still name his daughter what his ex suggested they name theirs. Sure, he's a selfish asshole, but that'd be a massive dick move even for him.)
Either way, the situation's still highly lulzy with the potential for all kinds of plot complications of the best sort. Hopefully Sango takes the king's story as an impetus to go further with her own uh, brand of diplomacy between the sea and the land.
