I have loved HIGH4 since their debut but this song has absolutely killed me. The dance practice killed me even more. I have always had my eyes on Sung Gu with his voice being so different from other male artist but this dance practice really solidified him as my bias for this group. I swore he was the main dancer of the group but learned that he is only a lead vocal and the leader. At the rate he is going, he might snatch main dancer from Alex. Tbh, I smell a solo debut coming from him in the near future.
