Thanks for the chapter!
In the LN Angie responds to Leon crying over Zola leaving as him must have been having it hard. Also, more details are given over Jenna's punishment. Normally she wouldn't be working in the fields, but after Leon told their father about her putting a bomb on his armor, it was decided that during the break she'd be helping out in the fields. Leon is a bit upset over her getting such a light punishment for almost killing him as he and his brothers have to help out in the fields every day they're home as the usual daily occurrence. Also, his sisters don't have to do field work being women, have rooms in the main house, and study with electric (or magical equivalent) lighting. While he and his brothers get to stay and study in a shack with a cheap oil lantern which gives off much less light.
BTW, explained more in LN later on but there are a lot less men then women in the Kingdom. Don't remember exact numbers but might be around one man for every ten to twenty-five women for those old enough to be in the academy and younger. After the academy the difference is greater due to the a lot of men dying in the numerous wars and fights against monsters and air pirates. Doesn't help that the women's group Zola is part of has their main objective of figuring ways of getting paid for getting their husbands/sons killed once tired of them. For example, Zola was going to be paid a lot of money from her "friend" from the group in exchange for Leon marrying her while having him become a soldier to profit from his death. The "friend" would have her fun with him, send him off as a soldier to the front line to die honorably in battle once bored with him, and being of a noble family would receive annual income for several years as compensation for her "beloved husband" dying honorably in battle. So Zola gets paid for selling him out, and the "friend" gets her jollies and stable income for years from his death. As for why women are favored it was partly planned, and the women becoming so corrupt and greedy from the favoritism was unexpected. LN explains it further on down so won't say who's telling background or when circumstances explained in the story, just there was a reason and an explanation given.
