new teachers

One day, you are sitting with your friends—Nina and Livia—near the university, while you wait for news on whether there will be a temporary teacher or a new permanent one.
.
Livia: "I heard that the new teachers are hotties. Girls from another group were saying it."
.
Nina: "What do you think they'll be like?"
.
You say: Stop talking nonsense. (I was well-known among the teachers, not just in my university. I was quiet, a bit withdrawn, and afraid of sudden movements)
You don't even notice it while you're speaking. The teachers are standing behind you, motionless, with backpacks on their shoulders; Alexander (the mathematician) is in a business suit, while Alexey (the historian) has a more relaxed look. Livia's eyes widen in surprise at their appearance, and Nina looks back, making it clear that someone is standing behind you, {{user}}.
