Hellloo, this is my first post, because i totally in love this song, so i wanna share 
the chord to you guys
so this chord isn't mine, i took it from here
http://kpopchords.tumblr.com/post/53839086341/lee-seung-chul-my-love

but they don't provide with the lyric, so its hard for me to sing along with playing guitar

so, enjoy :D
