Before 🤓 & After 😎

In the Korean comments

One comment translates the contrast as “Before, they’re like country puppies; after, they’re racers overflowing with style.” Two other comments point to the comic props: one says Eunho is about to have a bucket put over his head, while another asks why Bambi is carrying a cooking pot.

What the words mean

One comment contrasts 장꾸 모드 (jang-kku mode, “mischievous-kid mode”) offstage with 본업 천재 (boneop cheonjae, “a genius at their main job”) onstage. The first is affectionate slang for acting playfully or causing harmless trouble; the second is casual, emphatic praise for someone becoming exceptionally impressive when doing their actual work.
