First, before you watch this drama make sure you're interested in the Japanese language. This drama is more like watching it for learning, and also entertaining. But i, on the other hand didn't watch it for learning so think more about what kind of mood you have while watching this. Even if i didn't have the right mood, i enjoyed watching this drama because i think it was fun while watching and i got to know more about japanese and its hidden rules. But i think the mood will be even better if you are currently learning japanese, the drama will be more valuable that way i think. But the story is not only about japanese, every episode has a special situation that needs to be solved kind of, so we also see how this teacher somehow is kinda like a mother to her students, she help them and are always there for them. So it is a touching drama too, of people who tries to achieve their dreams and helping each other ;)
