Sweet Night是由韩国流行男团防弹少年团成员V（金泰亨）录唱的一首歌曲，亦是JTBC电视剧《梨泰院Class》的原声作品之一。
此曲是以Acoustic Sound为基础的INDIE Pop。 以不插电吉他为基础，后半部出现的V的哼唱和小提琴所构成的和谐音韵令人刮目相看。 就像歌曲《Sweet Night》的题目一样，这首歌表达了希望能给跌入无尽痛苦的夜晚的朴世路带去甜蜜夜晚的安慰
同时，网站还为大家提供了《Serendipity》曲谱下载
Sweet Night歌词：
On my pillow
Can't get me tired
Sharing my fragile truth
That I still hope the door is open
Cuz the window
Opened one time with you and me
Now my forever's falling down
Wondering if you'd want me now
How could I know
One day I'd wake up feeling more
But I had already reached the shore
Guess we were ships in the night
Night night
We were ships in the night night night
I'm wondering
Are you my best friend
Feel's like a river's rushing through my mind
I wanna ask you
If this is all just in my head
My heart is pounding tonight
I wonder
If you
Are too good to be true
And would it be alright if I
Pulled you closer
How could I know
One day I'd wake up feeling more
But I had already reached the shore
Guess we were ships in the night
Night night
We were ships in the night
Night night
