Heartswave shares the behind-the-scenes story of the collaboration with Seongchan

It is particularly eye-catching that the Heartswave members personally shared their thoughts on working with Sungchan. It was impressive to hear that everyone was satisfied because the result exceeded expectations. It seems the song's quality was elevated thanks to the natural blending of their respective strengths. I really want to see a performance of 'ALIVE,' born from this collaboration.
