please help

I just remembered that I was reading a manga like around 4 months ago, I forgot about it because it was still on-going and I was waiting for more chapters. AND NOW I WANNA READ IT AGAIN BUT I FORGOT THE NAME?? AND I CANT FIND IT ANYWHERE T_T
imma try to explain what the plot was about. I think it was some sort of high school, he was definitely a student and he was picking up fights with a new teacher that was smoking outside in secret, while sitting in a bush. the teacher was female and if I remember correctly she switched schools and was a new teacher there? but im not sure anymore. so basically the rest I remember of the manga was, that the school had like seperate places, for example a place where only the art people are at, a place where dancers are at,.. all I remember is that he was dancing, I think he was doing ballet but after an injury he stopped? or it was because of his mother, im not sure anymore. oh and there was this one annoying female friend that he had, she had serious problems with the teacher and was jealous of her because he was spending so much time with the teacher and he brought her to "their" secret room in the school.

PLEASE LET ME KNOW IF YOU KNOW THE NAME OF THE MANGA I WANNA READ IT AGAIN T_T
