Count to #SUNGHANBIN 🩵 #BOYNEXTDOOR

Why Koreans care

The counting is part of the song’s romantic joke, not just the challenge title: the narrator planned to endure only three times but has already done so five times because it is love.

In the Korean comments

The comments reveal that viewers recognize Sung Hanbin and Jaehyun as a missed pairing called 멍캣 (meong-cat, dog-and-cat). One comment identifies their roles as “the dog-like younger one and the cat-like older one,” while another asks for them to return as MCs; a separate comment hopes Sohee will join them next time for a 멍또캣 (meong-tto-cat, trio nickname) reunion.

What the words mean

When a commenter writes “이 조합을 다시 말아주다니” (i johabeul dasi marajudani, “you served this pairing again”), 말아주다 (marajuda) literally suggests rolling or mixing something up. Here it is playful fandom slang for putting together and serving up a desired combination of people again.
