Dear teacher friends,
Maybe some of you might not be the ones who are "into" Korean dramas but I have a recommendation. A Korean drama entitled "Master of Study" can be a guide for us, especially the secondary school teachers who will be dealing with difficult and rebellious students, especially those coming from the Normal Technical stream.
Probably, at the beginning of the series, it may be a bit boring but it's really a good drama to guide us teachers. Highly recommended by yours truly...
