CGDCT's mangakas definitely loves MILFs, which begin to harass schoolgirls after high doses of alcohol. But what I liked most was the innocent question "is she single?" in the middle of the scene, lol.
idc if she was my teacher i'd yell at her for stealing my food off my chopsticks after gorging herself with me and my friends hard work. zero self-awareness
Now this is the kind of stuff that might get you stabbed in a dark alley... or you might wake up in an ice tub with half your organs missing... never underestimate a food grudge =P
