Thanks for the chapter!
It's funny how awkward and shocked Milaine is over Leon being bullied when she had similar, albeit much lighter (was going to settle for making him remake the tea 3 times,) thoughts of making him uncomfortable. Glad to see someone female with high authority who's human, knows restraint, and isn't full of themselves. That Earl's daughter is a real piece of work blaming Leon for others' bad gambling and judgement. Has the same bad trait of the other academy women of complaining about the quality of something and insisting the person should pay more while completely ignoring whether the item in question was expensive or not in the first place, probably has no idea how to tell quality or price in the first place and sees only the inherited value of someone's family rather than their personal value or achievements.
Oh dear, Leon finally got a good excuse to lay into those girls and their servants. LN explains better but way back when when Angie was young and foolish, before Milaine straightened her out, she had similar views as the other girls and commoners were just somebody she heard or read a report about as she never had a chance to meet or befriend any of them back then hence the superior attitude and foolish words which she is now aware of how those foolish words indicated how insensitive and immature she'd been. Also, Leon had seen the queen during the Knighting ceremony so recognized her once he got a good look and being one of the few to pay attention to Angie's reaction, (not like formally introduced or talked with but he had noticed her standing beside the King.)
Btw, in case anyone wondering how slaves, ranked as property and not as citizens, can get away with laying hands, beating up, and being rude to nobility in the school is due to one of those unwritten rules Livia wasn't aware of. Basically, they're the favored lovers of the girls they're 'escorting', so they're like paper tigers using the position and authority of their owners to get away with things. If a boy who isn't the Crown Prince beat up one of the slaves, no matter how justified the reason or even if in self-defense, that boy would be black listed by ALL the girls in terms of being a marriage partner and the girls would go out of their way to make his life even more of a living hell. So if that boy even tried to complain it'd just get him in trouble with the girls. Thus the slaves are real cocky knowing the boys can't defend themselves properly and that their masters will cover for them as long as they don't go too far or are just following orders. Hence why Leon and co were laughed out of the party after being physically thrown away instead of outrage towards the slaves for assaulting nobility.
