"kekekeke... ne, ne. don't worry oppa! i'll waiting here for you until whenever.."

"really? ne, i'll keep your promise".

Thats last time Yunho talking to Changmin when their just together. as well, Yunho will going to Germany for taking his scholarship and forward his study for 5 years there. while changmin? her just getting lonely because of he will preparing to go.

But, could changmin wait for 5 years? even more than 5 years? we doesnt know but, seems that impossible. Since young age, Changmin had eyes cancer. no one knews about it, except her family and her beloved friends, Seungyeon. Doctor was said that her life chance is too little, except her did huge operating. but, her will losing her slight and too risky for life. Changmin knews about that, so her dont give everyone hope to saw her in future.
