On the October 15 episode of JTBC’s “Night Goblin,” B1A4’s Jinyoung and Gongchan featured as guests.

Jinyoung, who is known for his excellent songwriting skills, picked up a guitar and spontaneously composed a song for the show. He added lyrics with some help from Lee Soo Geun, and the song was completed with a rap written by NU’EST JR.

Although the exaggerated vibration from some of the cast members drew laughter from viewers, a soothing track perfect for the autumn night was created in a very short amount of time.
