壹般來說.如果外國人要表達類似於我們說的唯壹或者壹生至愛的話,都用 you are the one 或者是說 my forever love.很少用 the only love的.
所以.
第壹句：
I will always love you(因為這句其實就是歌詞,所以,在外國人看來,還會比較romantic.）,cause you're the one.../ cause you'll be my forever love...
第二句：
I love you,this is not just saying something...
(我愛妳,這並不是說說的事情.）
I'm not kidding you or just saying something,it is a truth that I'm falling in love with you and this love will be forever...
