作曲 : Jong Seok Lee I thought we were safe in our untouchable fate I thought we would see leaves falling every year I thought of the eternal flame give you my last name I believed in our first love then 2nd love came along they say first love's innocent without understanding we cried from all the fighting, breaking then forgiving we learned from trials and errors from our first love it was rough that’s why your 2nd love's warmer than your first you rearranged my heart puzzled it back from my first you filled empty trails with new songs I was lost warm heart deep affection with loving expression this too became distant memory without a ending summary they say first love's innocent without understanding we cried from all the fighting, breaking then forgiving we learned from trials and errors from our first love it was rough that’s why your 2nd love's warmer than your first
