Nanka Kawatteshimatta Osananajimi - Ch. 1.5

So it was a acid attack.
I know it was obvious, but in the main manga they didn't really make us see what happened and how, it felt like it could have been a incident in the chemical classroom separated from the jealous girls.
In the main story the attackers and event itself didn't appear, the author gone around it.
