It’s a song that actually lifts my spirits whenever I listen to it when I’m feeling down, haha... It’s crazy.

That's the song that even Yoo-nim seems to enjoy singing and dancing to.

Anyway, I posted a Two You post right below...

Teen Top in early 2012 with "I'm Going Crazy"

And to To You..

The following year, she was the girl with long straight hair again..

It elicited a very positive response.
