The first part was a fabulous building up story it wasn't new but refreshing and wel written the actor fab.... But the 2 part did they switch writers? Did someone told them their budget was cut what happend? The story is so not logical like the jammed 4 seasons in to 4 parts? The prison scene? The other highschool kids? Moving in to Seoul? Looked like they where short of money and somebody cancelled the show!! What a shame I would have accepted the end but not like this noway... Worst written show after a fabulous first season. The director must have been high on something during the shooting of the serie every blind person could have noticed it was a crap second season really crappy.
