What does one think while going to a movie, that they might connect to the character for its pain and enjoy its happiest moments. And more of all to watch the favorite actor for 2hour is actually a joy. But this movie had me like when is it going to finish.. It was plainly BORING for me.

Actually, it took the whole hometown and all the characters his father, teacher, friends, enemies, the girl he liked, and the girl that liked him, and hence it got all tangled up.
The movie is too long and the character is just fighting in the present. Half of the character's past is not shown so it's difficult to connect to them. The fights are not comical, but frustrating. It should have rather concentrated on a few characters than mess up with all.
The romance seemed a bit imposed. It was OK when it was one-sided showing the first crush feels but in the latter part it just came out of nowhere without any connection happening. The father-son story was also not developed well.
since I didn't enjoy the story I didn't like the acting as well, nobody moved me.
The only good thing I liked about the movie was the rapping of Hak Su
