Not a comment on this chapter but the series in general: I get it goes against the gyaru aesthetic, but the lab inappropriate attire is bothersome. I don’t think it sends the wrong message since it obviously isn’t a serious manga, but it could.
Hotpot with the autoclave? Wtf?
I did theory partially to avoid these problems (serious). I don’t know what rules my friends in the laser lab had. I mostly remember sending students home because of clothing faux pas, particularly open-toed shoes.
