Lee Seunghyun is still very much the good boy who loves his uniform with all his dedication and hard work, his life is still the same which was 1 year ago except for the addition of the one bad boy Kwon Jiyong who have by the time span and his passion become a popular music producer but whose bad boy image have failed to leave him though he is now only Lee Seunghyun' s bad boy.          

Jiyong is back once again to prove that love above all is just a beautiful thing and it should be preserve and cherish forever. That no love is wrong. This time he had Seungri with him so it might not be so hard after all, right? Oh, Kwon Jiyong has got it wrong all along.

" Music heals every wounds "  That was what he always used to say. But for him, he was his music and he was his wound. Then will he be healed?
