Omaera Zenin Mendokusai! is getting a live action adaptation.
I actually found out about the manga because of the news it was getting an adaptation. It's another "students in love with their teacher" romcom. Teacher isn't as dense as Yabecchi, nor as efficient as Shiota, he actually wants his ara coworker, but the girls keep teasing him.
It's from the same author of Megane na Kanojo, which got it's own OVA adaptation back then.
