HELP!! I DONT REMEMBER THE TITLE

Its a manga I've read quite long ago but here are the few details I remember well : the pov is from a girl who has impulses to kill her friends and classmates . The ml/love interest is this teacher who is into degradation and humiliation, I think the ending was healthy, I read it long ago but since I made my acc here I can't find it TT
