K-pop Lyrics

Yesterday all my trobles seemed so far away
Now i looks as though they're here to stay
Oh i believe in yesterday
suddenly i'm not half the man i used to be
There's a shadow hanging over me
Oh yesterday came suddenly
Why she had to go i don't know she wouldn't say
I said something wrong now i long for yesterday
Yesterday love was such an easy game to play
Now i need a place to hide away
Oh i believe in yesterday
