정한X조슈아 (SEVENTEEN) '12 o'clock' Official MV

In the Korean comments

Two comments pinpoint the moment where the pair appear to collide. One reads, in translation, “The part where the two of them collide? The vibe is seriously so good,” while another says the video feels like “a decadent youth drama” and returns to that same moment as its highlight.

What the words mean

“느좋” (neujot, “good vibes”) abbreviates “느낌 좋다” (neukkim jota, “the feeling is good”). Here it means that the collision moment has an especially appealing vibe or aesthetic; it is casual internet slang, not simply a statement that someone feels well.
