Looks Can Kill ⚡️

In the Korean comments

One commenter says they first discovered both IVE and Yujin through the “HEYA” music video, where her dancing, expressions, singing fundamentals and energy stood out; they particularly value the sense that she enjoys performing and hope to see her promote solo someday. Other comments repeatedly play on 댕댕이 (daengdaengi, puppy), calling her 유댕 (Yudaeng), 안댕댕 (An-daengdaeng) and “Captain Puppy”—affectionate nicknames built around Yujin’s surname, An.

What the words mean

“괜히 유진이겠어” (gwaenhi Yujin-igesseo, literally “Would she be Yujin for no reason?”) is not expressing doubt. Here it means “There’s a reason she’s Yujin” or “Of course Yujin delivers”—a casual, emphatic compliment that several comments echo.
