I would recommend Hit the top to anyone who want to have a great time with an entertaining drama, The story line is funny and refreshing and you will fall in love with the characters, even "the bad one".
Hyun-jae story get more and more touching through the episodes and you'll probably catch yourself laughing, smiling and crying with him.
Even though the story line does not feel completed, You should watch it If you want to have a good time ! (Sorry for my english)
