Is it a dream or reality?

In the Korean comments

One top comment reads, in translation, “The pair choreography where they face each other is so cute.” Another commenter says the two looked so alike that they frequently confused them when first becoming a fan, although they can now identify each from behind.

What the words mean

“얼굴합이 존맛이야” (eolgulhabi jonmasiya, literally “the face combination is delicious”) means that Jeonghan and Joshua look exceptionally good together. It is casual, exaggerated fandom slang; “delicious” praises the visual pairing rather than taste.
