Shake it 💓

In the Korean comments

One top comment reads, in translation, “Gayoung is already very pretty, but in a few years she’ll be untouchable. For now, that’s hidden by her kid-plus-young-girl side.” Another says she has recently become much more “older-sister-like”—a specific contrast between the youthfulness commenters still see and the more grown-up impression emerging here.

What the words mean

까엉이 (kk aeong-i, an affectionate nickname for Gayoung) is a deliberately cute variation of 가영이 (Ga-young-i, Gayoung). The comment “진짜 너무 이쁘다니까엉” (jinjja neomu ippeudanikkaeong, “I’m telling you, she’s really so pretty”) also bends the ordinary ending 다니까 (danikka, “I’m telling you”) so it echoes that nickname; it is playful, affectionate wordplay rather than standard phrasing.
