Looks Can Kill - IVE's YVES

In the Korean comments

Several comments single out 음색 (eumsaek, vocal tone) rather than singing ability alone. One reads, in translation, “Her voice is really soft,” while another says, “Wow, her vocal tone is so beautiful.”

What the words mean

The title’s 괜히 이브겠어 (gwaenhi Ibeugetseo) literally asks, “Would she be Yves for no reason?” Here it is a casual, admiring rhetorical expression meaning “She’s Yves for a reason”—her performance lives up to her name.
