deyi secondary school is an amazing school for you if you want to get detention for being 3 seconds late to school. the toilet on level 1 smells like shit, the moment you enter it you’ll start vomiting profusely. the school has enough money to buy tvs to put in the hall for fuck knows why and the videos they play look like something they made in 2001 (which they probably did), but they apparently don’t have money to get actual tiles for the floor. our classrooms look like rooms that haven’t gone through renovation yet. the floors are full of dirt and cement , one would think this school was built yesterday. the boys for some reason think that they look extremely attractive with mushroom hairs. don’t even get me started on the girls with bangs that look like a bugs feelers. for some reason everyone is obsessed with tiktok , especially the girls who also happen to think that pulling the skirt al the way up to their breasts is a new form of fashion. our band is cool, but 3/4 of the school is in band. all you have to get into band is probably tell the seniors that you like their hair or something.

A school where XMMs are always taking photos in the toilet and YPs thinking they have a massive fanbase, its also where you can find teachers being toxic to other classes students which is very professional
