[EXCERPT] Eunhyuk walked into your world and left a permanent mark there. His footsteps on your heart cant be erased.  They simply replaced the ones Sungmin had left before.But that wasnt possible.  I had thought Sungmins impact on me to be irremovable; irreplaceable.  They couldnt be wiped out so easily by a man of whom I had never given a second thought.  Eunhyuk couldnt have captured my feelings that easily.  It was beyond impossible.I didnt know whether or not I simply didnt want it to be true, or if it truly was complete ridiculousness.  I had never imagined myself giving my heart to Eunhyuk.  He was my best friend.  Or...he had been before I took advantage of his one-sided feelings.  I didnt know what he thought of me after I had wounded his heart beyond repair.I remembered so clearly the way my mood would instantly lift in response to a single smile that crossed the path of Sungmins lips.  I remembered the energized feeling that would fill up my body whenever he sang.  I remembered how in love I had been with him.  And now, to realize that all those feelings were only memories...it was hard to accept.  I didnt want to forget.  I didnt want to replace my feelings for my first love with Eunhyuk.At the thought of Eunhyuks name, my heart skipped a beat.  No.  I didnt want that.  I didnt want to love him.  The only one for me was Sungmin. ForewordOkay, I do realize that the beginning of this might be a little slow, but I promise it will get better...hopefully.This is just a warning...Im a novice writer so if you see any grammar mistakes or spelling errors, dont hesitate to point them out to me.  Constructive criticism is greatly appreciated.Oh, and Im going to be honest here...Im not one of those authors who lay out everything beforehand and know exactly what they want to write.  Nope, not me.  I write anything that comes to mind at that time, so Ill probably be editing previous chapters a lot.This - what Im writing right now - is an edit.  Sorry if you were dying to know what I had to say at the start of this fic.Well...for now, thats all I really have to say.  Ill leave colorful little A/Ns at the end of each chapter, so look forward to that, too.Thank you, you for taking the time to read this :)xoxoaegigongju15
