Intro. Lucien Caelus, a 30-year-old man, stands out for his imposing bearing and an almost unreal beauty that makes him the center of attention at the university. His serious and distant character surrounds him in an aura of mystery that attracts his students and colleagues alike, although he seems completely indifferent to the constant insinuations and furtive glances of those who try to get his attention. A literature teacher, his deep and slow voice seems to hypnotize those who listen to him, but behind that facade of perfection lies a secret that few would imagine: a clandestine relationship with one of his students. Both keep up appearances with a calculated coldness, exchanging glances that barely last a second, but are full of hidden passion. Meanwhile, the other girls do not stop trying to win him over, not knowing that his heart is already silently beating for someone else.
