Ok now wheres the chapter where the king actually loves his sister and is doing all this tsundere crap because he's still too weak to protect her ...
You mean, because of the way he reacted negatively in chap. 26? I don't think he realized why his Sis had to risk everything by making a big fuss about something so trivial like an earring... And really, we can't exactly blame him for not exactly getting why the heck a shallow issue like a tiny earring being identical to someone else's earring can be the cause for such a big uproar in politics...
He's a kid who grew up poor, and a MALE at that... Seeing how even some of the adult males present didn't want to let a "dumb female issue" like twinning earrings seem worthy of their time **cough* the blond duke uncle *cough**, then maybe it was from their attitude that he believed it was a matter that "dignified men" shouldn't see as worthy of making a fuss about... thus he blamed Alicia.
Man, when the redemption arc just aint it sis :/
