'Sejeong-ah', I said. It took her awhile before she respond to me.
'Unnie, your coming back right?',Sejeong asked with a hint of sadness in her voice. 
Feeling her sadness, I nod eventhough Im not sure when will I be able to comeback.
'Then I will wait for you not matter how long it takes', Sejeong said in a low voice
'If thats the case then I will definitely comeback, I promise',I said while raising my pinky to seal our promise.
