Promises: are they able to be kept for ten years? Memories: are they possible to be relived?

The girls before were innocent, bright and full of youth; they spent their days with only each other, but the joy they had was everything they needed; their friendship was beyond what words could define: promises defined it. But with the passing of time, the girls found themselves to be changing; and in the blink of an eye, they are all grown up by now; some are married while some are still in search for their significant other- one has already given up, and another not even beginning to try yet. It is only then, they begin to find the need to travel back to their past. They decide to leave their lives behind for a moment, to enjoy the last of their youth: to dwell in the past that they used to spend together with their hearts as one, those precious times that their nostalgic hearts still cherish and are yearning to remember; all that before their eldest finally turns thirty.

"기억해 _(Remember) /

Me gustas tu"

So their song really made me feel like writing something. That song is too beautiful- ugh I can't explain how much I feel for it really. My old habit of starting new fics even with incomplete existing ones is returning... Asdfghjkl help. Lol. I'm not sure what I'm writing man, here goes... 

UPDATE 15/08/03: Change of title. I added in 기억해 which means 'remember', and it's the Korean title of their song "My Buddy" in which the lyrics absolutely fit this plot. And the Korean title suits it well too, as well as how it suits the song. 

UPDATE 16/02/19: Change in foreword. Might hint a change in story concepts.
