"Hello" is the title track of Younha's full studio album, which will be her first since 2012's 'Supersonic', and she's collaborated with producing duo GroovyRoom for her return. In the lyric teaser video, a piano melody plays over an interesting scene with a glass and the message "Paper Plane: Hello."

You can expect "Hello" to come out on December 11 KST! Stay tuned for more teasers until then!
