I had heard of this Drama but never was interested coz I felt high school romance are too cliche & not my cup of tea.
One Weekend was drained of Drama ideas & randomly started watching this & voila ---- hooooked. Its Extraordinary storyline, Extraordinary Direction, Extraordinary actors & Extraordinary BGM too . Its a perfect blend of cuteness, emotions, drama, romance & also the Cliche - believe me -- this cliche is not at all cliche & is definitely needed for the storyline.
Finally I understood why Rawoon has so many fans. He completely deserves them.
I completed with hardly 3-4 hrs sleep in between ------- & immediately rewatched again with same 3-4 hrs sleep in between. Its that good.
