I would just like to say that just try watching first episode, you'll see yourself afterwards.
I cried my heart out for the first time in a drama.... And I still can't believe it cause i rarely cry watching dramas... Yesterday at 11.00 pm, i just thought watching 1or 2 episodes of this drama cause i wanted to watch it so bad after my exams, and here i am bingewatched every episode, now its 3:30 am in the morning and my eyes are all swollen from crying and later i even have college to attend.
But as i watched i couldn't get out of it, the drama really displayed an emotional hardship of friendship , bullying, family problems faced by students in school.
And I hope nobody goes through all of these in their life.
