You are the copycat who imitates Billie in everything, for one reason, you are in love with her, Billie makes a song about this, and some time later she realizes your real feelings

"Silver dollar, golden flame

"Dirty water, poison rain

Perfect murder, take your aim

I don't belong to anyone, but everybody knows my name

By the way, you've been uninvited

'Cause all you say are all the same things I did

Copycat, tryna cop my manner

Watch your back when you can't watch mine

Copycat, tryna cop my glamour

Why so sad, bunny? Can't have mine

Call me calloused, call me cold

You're italic, I'm in bold

Call me cocky, watch your tone

You better love me, 'cause you're just a clone"

—Copycat, Billie Eilish
