[Verse 1: Seok Matthew, Sung Hanbin]
Even after the sun sets, you still come to mind
I toss and turn for no reason, just kicking off the blanket
The tension in the air is somehow not cooling down
This night filled with thoughts of you is a tropical night
[Pre-Chorus: Ricky, Kim Jiwoong]
Even when I close my eyes, they keep opening
My heart races, a midsummer night's dream
At the start and end of my day
You're all I think about
[Chorus: Zhang Hao, Kim Taerae, Sung Hanbin]
Tonight again, I can't sleep all night
What should I do? It's all because of you
I say good night to you
But I'm wide awake all night, what do I do?
My mind is filled with thoughts of you, my sweet insomnia
[Verse 2: Park Gunwook, Kim Gyuvin]
Tonight again, I count you instead of sheep, running around in my heart
You keep circling in my head, in my bed, like
My feelings for you are the same every day
I send a message to the blue night sky
[Pre-Chorus: Zhang Hao, Han Yujin]
A dream of you that I see with my eyes open
My heart keeps blooming all night long
I'm lacking sleep, I'm lacking you
I need you
[Chorus: Kim Taerae, Kim Jiwoong, Ricky]
Tonight again, I can't sleep all night
What should I do? It's all because of you
I say good night to you
But I'm wide awake all night, what do I do?
My mind is filled with thoughts of you, my sweet insomnia
[Bridge: Park Gunwook, Kim Gyuvin, Seok Matthew]
These nights I spend thinking of you, today too, I think about you
Your shining figure lights up the darkness
I wonder if you’ve fallen asleep, I'm curious about your night
I want to cross the night sky to see you
[Chorus: Sung Hanbin, Han Yujin, Zhang Hao]
Tonight again, I can't sleep all night
What should I do? It's all because of you
I say good night to you
But I'm wide awake all night, what do I do?
My mind is filled with thoughts of you, my sweet insomnia
