RWRB 王室緋聞守則 IfILoveYou
從 Henry 於午夜離開 Lake House 那一幕開始，背景音樂用的是經典音樂劇「旋轉木馬」(Carousel，1945) 中的名曲 If I Loved You。
原曲很長，後來許多翻唱版本都只擷取中間最動人的片段：

If I loved you,
Time and again I would try to say
All I'd want you to know.

If I loved you,
Words wouldn't come in an easy way
Round in circles I'd go!

Longin' to tell you,
But afraid and shy,
I'd let my golden chances pass me by!

Soon you'd leave me,
Off you would go in the mist of day,
Never, never to know how I loved you
If I loved you.
