OK, nobody is asking this so I will:
WTF magical school is this? 28C lowered to 23C? Non of schools I gone to even had a such fancy thermostats - just the basic wax based simple ones on heaters - no fucking AC to even see - and if there was - it was only for teachers room lol. So if there was 18C in winter in classes it would be a good day - cause if you are to cold just dress warmer, at summer you simply melted like everything else cause no AC.
Also a side note:
So this is what happens when both the girl and the dude have less than 1 functioning brain cell/are dense idiots. Part of me wonders how a harem would look like if both the dude and all the girls were like this two - thou it would probably implode in like chapter one - to much denseness too close to each other, would transform into like universe eating black-hole.
