The April 20 episode of KBS' 'Hyena on the Keyboard' continued to show JB's song making process. The leader of GOT7 nervously presented his self-composed track to J.Y. Park for review. Fortunately, JB was given positive feedback and compliments from the JYP producer. 

The episode also showed JB performing his song for the first time. "Rainy" compares the depressing emotions of drifting away from love or youth to a rainy day. 

Watch JB's soulful performance in the clip below.
