Didn't expect this to be so good.The characters are so lovable and it taught me also so much about South Korea's private academys.I was shocked to learn that there are effectively star teachers and these stars academy and that it's a 16B USD business yearly.To be frank this educational system focuses only on the elite and it's sad to see teenagers finishing studying at 10 or 11pm.Despite all these efforts the SOuth Korean educational system is not among the best as they push these children to the brink.Countries like Finland or Estonia are one among the best concerning education and they don't create elites where people from their capital cities or countryside will have access to the same education and teaching.Coming back to the series it is a must see and very well done.Great job.
