Looks Can Kill (eyebeam ver.)

In the Korean comments

One commenter singles out two moments to watch for: Yujin’s punch and Iseo’s dancing. Several comments also call the pair “헤헤즈” (Hehejeu, the duo’s nickname), using it as shared fan shorthand without explaining it.

What the words mean

In “너무 귀엽잖아” (neomu gwiyeopjana, “they’re just so cute”), the ending “잖아” (jana, “as you know”) is not really asking a question. It casually and affectionately treats their cuteness as something everyone can agree on.
