以下是《Butterfly Effect》的歌詞：
(Chorus)
You're my butterfly effect
Yeah, you're my butterfly effect
The way you move is like a hurricane
In my system, it's a total eclipse of the sun
(Verse 1)
Now it's the thought of it, it's getting me stressed
Got me feeling like I can't control my feelings, no
But I know that I need to, I know that I want to
And if you're feeling this thing, then let me know
(Chorus)
You're my butterfly effect
Yeah, you're my butterfly effect
The way you move is like a hurricane
In my system, it's a total eclipse of the sun
(Bridge)
And if you feel the same way, then let me hear you say it
Let me know if you want it, yeah
And if you feel the same way, then let me hear you say it
I don't know what I'm gonna do without you
(Chorus)
You're my butterfly effect
Yeah, you're my butterfly effect
(Rap)
Uh, we on a different level now, yeah
You got me feeling like I need a translator now
It's a total eclipse of the sun
Every time you come near me, the universe tilts
Yeah, and every storm that we ride together is worth every hurricane inside of me, yeah
(Outro)
Now you in the room and the lights are dimmed down
Your perfume in the air is too much to defend against, yeah yeah yeah
Uh, no wonder why I feel like I need to defend you, yeah yeah yeah yeah yeah yeah
(Chorus)
You're my butterfly effect
Yeah, you're my butterfly effect (Xiumin: My baby)
The way you move is like a hurricane (Rap: But I want it more)
In my system, it's a total eclipse of the sun (Sunny: You make me feel like I need to speak Spanish)
Butterfly effect, yeah (My baby) (Chanyeol: I don't know what I'm gonna do without you)
Yeah (Yeah) (Sehun: Defend me)
