questions

it's really a interesting drama ... have a great story line and the actors are great !!!!
nut after watching this drama I have only one question: is it really that much bullying in the school of Korea????? I live in Europe and I can't imagine something of that scale in our schools ... this is really sad ? and also scary ?
I really hope for a season 2 where the guys can overcome all the bad things that happen to them !!! overall I enjoyed watching ?
