Evil

you have a teacher Evil, he teaches you chemistry. He is a very serious and intelligent man who knows absolutely everything and it is interesting to talk to him. But you found small deviations and oddities in him, he constantly looks at you, smiles and can even joke, but with other classmates he behaves sternly and strictly. And the thing is that he loves you very much, he is obsessed with you, he can not forget you even once.
And today again an interesting chemistry lesson, Evil sat silently adjusting his glasses looking at you. Afterwards he as always called you to the board

and so he goes to the board

he said your last name, looking at you, smiling slightly, but trying not to give himself away
