Thanks for the chapter!
Poor Angelica. The way her followers act is worse than the way women like Zola treat men. Cozying up to her for months or years, and yet when she needs their help and support they either withdraw silently or made fun of her for going against the prince or objecting to another girl acting so affectionately with her fiance for years. Considering how many more women there are then men polygamy should be fine, so would be a hoot seeing Leon marrying both Angelica and Olivia as they seem to get along well. Although since Angelica is a Duke's daughter and Olivia the true Saint he'll probably consider them outside his reach and not make any serious moves towards either.
BTW, been matching manga progress with LN and in LN it seems that Angelica wanted to try stuff from the food stalls before but was prevented by her followers, who secretly went often, with excuse that it wasn't fitting for a woman of her stature. Also, part of reason Leon wants a demotion instead of promotion despite benefits isn't just the rank of the woman he marries changing. While rank hath it's privileges it also has it's responsibilities. Higher rank means he has to pay higher taxes and the standard for the floating island he owns after being fully developed and earning income would be that of a baronet. Also, in the event he's called into one of the numerous battles that occur several times a year he'd be expected to provide and maintain himself an airship for the battle. So, for example, Angelica's father Vince, being a duke, is likely expected to provide 5-10+ airships if called on.
