Younha appeared on 'Yoo Hee Yeol's Sketchbook' on November 13 and revealed that she had recently been in a relationship.

First, Yoo Hee Yeol complimented her on her transformation into an autumn lady, calling her elegant and pretty.  She replied nonsensically, "Because it's late autumn.  I gave the feeling of a woman getting slapped by tree leaves."

She then suddenly added, "I will act calmly.  Like my normal personality," with a bit of a dark edge to her voice, so Yoo Hee Yeol asked wisely, "Did you break up recently?"

She replied, "That's right.  Didn't I text you?  Dripped in the sensibility of daybreak, I sent Yoo Hee Yeol a text saying I've broken up.  Yoo Hee Yeol sent a reply, 'Okay, you did well.'"  

The song she had written after the separation was "What Left Me Then," which she proceeded to sing. You can check out her performances here.
