Having revealed his first solo mini-album and the music video “Girl” just two days ago, Kim Hyungjoon has released the teaser for his second music video “oH! aH!”. The SS501 maknae also successfully completed his first solo showcase on March 5th at the Kahya Theater that had a capacity of 578 seats.
Hyungjoon revealed at his showcase that he wanted a new type of sound and he found it in the title song “oH! aH!”. Initially, he was worried about it being too different and lacking the popular appeal. However, as he shot the music video for the song, he felt that “this was indeed the title song.”
