It's a shame! This drama misses a good 10! I will explian ... First of all, the beginning was amazing and we quickly became addicted ! BUT WTF with this ENd ?! -_-' The problem was not in the cast, because there are very good ! I love all of them ! We could feel the friendship between the student and the teachers ! The music was good ... Kim Bo Kyung is a very great singer ! The Story ! Yess ... For sure, the beginning was very good and the middle too ... The stories were good and there was some funny scenes ! But The end wasn't good at all !! I'll give you my impression. For me, the filmmakers did not know how to finish the drama ... then they soon find an end! But I always felt that there was no final! The last scene does not cut anything! This is why I am disappointed! Bur I give an 8 thanks to the beginning and Thanks to the cast !
