"Your singing is loud for everyone to hear while mine is quiet and something no one even heard"

Lee Jooeun is the you don't notice in the corridors of school while Kim Jonghyun is the one everyone centers around.

Jooeun is quiet,shy and scared of the world while Jonghyun is the opposite he's loud,out-going and he confronts the world with a smile full of confidence.

They are the complete opposites of eachother.

The only things they have in common is that their names starts with the letter J, they both have family problems and they both have a big passion for music.

But when they get paired up for a project what will happen?

Will their diffrences tear them apart?

Or will they heal eachother wounds?
