For the first time since their 2022 debut, H1-KEY are trying their hand at electronic pop. Punchy synths, heavy bass, and a fast-moving beat back the members’ rougher, more powerful vocals, a big shift from the bright, youthful sound of songs like ‘Rose Blossom’ and ‘To. My First Love.’ The MV leans into the change with a cinematic sci-fi concept that turns the four members into fierce warriors. The group brought the new song to the stage for the first time on KBS 2TV’s ‘Music Bank’ the same day.
