I'm in the UK and initially I was put off by the eccentric characters and weird storyline but in 2 or 3 episodes I was finding this series funny and well worth watching. It was a touching romance and a brutal picture of how parents can behave in South Korea. Certainly an eye opener. I appreciated the fact that suicide wasn't shied away from and that sometimes the youngsters were the best people to help. The damage done by teasing, gossiping, and plotting was chilling to watch.
I warmed to all the main characters and thought they were acted with thoughtful evolution through the series. You can still fall in love if you're a bit weird. All the masses of students who did not have speaking parts did seem to represent a real institution. So well done everybody.
