A duet song created by Jinyoung and Wonpil while reminiscing about their trainee days

Maybe it's because we're best friends, but throughout the work

It looked really heartwarming to see them recording in such a friendly atmosphere, being considerate of each other.

If you watch it, Jinyoung says he really likes Wonpil's voice and really wanted to sing this song with him.

I could feel how deep their friendship is.
