I was thinking that those were some "friends" of hers who straight up abandoned her to the wolf, even though they knew it was her first time in this sort of setting. Granted, they were inebriated and drunk out of their minds to make good decisions as well, I'm sure, but still. You don't ever abandon your girl friends as a woman, and hell I'm saying this a guy, simply having seen this sentiment be echoed by many women over and over again. It's like a part of "sis code" (like bro code) that you just don't break.
Glad that Sensei realized that those weren't her friends, but enemies since they failed to care for her safety lol. Thing is, she was actually rather charmed by this guy when he said that she was cute in particular, but this dumbass ruined his chances by taking sumn about a "titty sandwich" lmao. It's her first time, dude. Have some delicacy.
