On the May 21 edition of MBC's 'Radio Star,' Younha revealed that actor So Ji Sub once appeared on her radio program, 'Younha's Starry Night,' and even gave her presents!

She said, "I featured in one of So Ji Sub's songs, 'Picnic,' so he appeared on my show for me.  He brought a cake he personally baked and a necklace."

Kim Gu Ra, ever careful about the details, said, "He has a bakery."  She nodded.  He continued, "So he didn't bake it personally?" which led to complaints from other participants on the show for ruining the moment.

In addition, Younha performed a song from the Disney movie 'Frozen,' and do not fret! It was not the ever popular song of covers "Let It Go," but the other cute track, "Do You Want To Build A Snowman?"  She even did the voices and sound effects as she played on the piano, showing how much she loves the song.
