"If" is the first SNSD songs (TaeYeon especially) i heard
I first heard this song when i was watching Hong Gil Dong
to me the song is very touching and full of emotion (sadness),
cause this song always came up when there is a sad scene in the movie
From this song i started to know about TaeYeon and finally all SNSD's members

Even i didn't know what the song telling about back then, but it makes me wanna cry everytime i hear this song
Now I can really understand the meaning, i'm very happy.
Thanks for the translation. JJang !
