#BirthdayWish for Lee Eun-kyul

In the Korean comments

Several comments repeat “이은결은 매지컬” (I Eun-gyeoreun maejikeol, “Lee Eun-gyeol is magical”) like a refrain; one specifically says the clip brings that song to mind. Another playfully reverses the expected roles, calling HAEWON the magician and Lee Eun-gyeol her “beautiful assistant,” while a different comment jokes that his magic must be real because “Oh HAEWON comes out of his hand.”

What the words mean

In the comment describing HAEWON running over and going “짠” (jjan, “ta-da”), the word marks the moment of a reveal. Here it is a cute, casual flourish, not the unrelated adjective meaning “salty.”
