There are many instances where in a k-drama I've seen the villain approaching a certain important figure's family to use that as a threatening, but this is the first time where I've seen what you call a 'hero' do it!!!
Okay so I'm on ep 14 and the story aside from the teachers it focuses om the 4 VIP students and other parts the 4-5 other students, and what I understand is if we leave out these 9 students, the rest of the school does what these people do, first when Tae Ra and Ye Ri bullied Soo Ah, everyone was on their side and when the news about Tae Ra's forged college application came, everyone went against her and went by what Ye Ri said, but when Tae Ra died, they gave flowers to pay respect which I get, but as soon as Beom Jin accused Ye Ri, everyone went against her without thinking one second and not to mention, in the beginning episodes where he Mr. Ki conducted the A B C quiz and everyone automatically sided whichever side Beom Jin was in. Even though almost all of them did real bad things I understood the sad reality of the people behind who just go with what they hear and can change sides and color without even giving a thought one second, I understand they kind of rule the school, but you too have brains people. Not complaining about the drama overall though as I love it.
You might not be very fond of ep 16 for the last line you just gave, you'll feel happy but.........you'll see...
