What happens when you bring two schoolboys from different backgrounds that hate each other together.

You get a big mess and a amazing love story.

Leeteuk is a rich trouble maker that has the principle up to his last thoughts.Yesung is a rich straight A student who only cares about what college he will get into.

But one day Leeteuk get's into trouble that can't be fixed and gets kicked out of school for 3 days and is told when he gets back he has to take his grades serious or they will throw him out for good.

Leeteuk could care less but his self image farther threatens him that if he fails this time he will no longer be welcome in his house.Yesung who needs one more thing to put on his college application to make him look good, so he takes up tutoring and is hired by a rich man to tutor his dumb trouble making high school son.

Yesung arrives to the address the man gives him and finds out the student he's tutor is no other then the schools trouble maker Leeteuk.

Will Yesung stick to the tutoring job???

Will Leeteuk take what his dad said seriously???

Will Yesung and Leeteuk get along or will it become more then that???
