Vocaloid: Gumi
Lyrics:

Say "Hello,
"Who are you?"
And we'll start from scratch again
"Gotta go
"Talk to you soon!"
Day by day, I'm fading away

We get along just fine
I say everything you like to hear
"It's funny how much I
Feel like I'm looking in a mirror"

I can't remember
Who I am
Everything's a blur
Take me over

I'll become what you like
This is what you've wanted, right?
Sacrifice all I know
I will teach myself to let go

Whoa...
Copy that copycat

Say "Hello,
"What's up with you?"
I'm starting to talk like you do
Here we go
I'll be gone soon
Day by day, everything has changed

We've grown a part this time
I can't figure out the reason why
"It's funny how much I'd
kinda like to see you cry"

I can't remember
Who I am
Everything's a blur
Take me over

I've become what you like
I am what you've wanted, right!?
Sacrificed all I've known
I have taught myself to let go

Whoa...
Copy that copycat
