(ノ´▽`)ノ♪ "It's not about the money money money
We don't need your money money money
We just wanna make the world dance
Forget about the price tag
Ain't about the uh cha-ching cha-ching
Ain't about the yeah b-bling b-bling
Wanna make the world dance
Forget about the price tag" (*゜▽゜ノノ゛☆

Still...At least she told him not to give up, so I think there is still some hope for his little plan.
And by the close, she starts (although perhaps it's in response to his *a-hem* 'technical skills') calling him "Onii-Chan.", plus she tells him not to give up.
