KISS OF LIFE has me thinking about Natty, which has me thinking about Idol School, which has me discovering something in this performance of "Ah-Choo" from the show.
Does Jisun perform Yein's "I'm not good at cooking, but I'm working on it" line ...
... with the choreo changed from a FIGHTING! fist pump to ...
... double OKs?
It makes total sense because, as we all know, Jisun is a complete badass in the kitchen. Evidently, she's a complete badass on survival-show stages, too (if you watch her fancam, she does the normal choreo at rehearsal, keeping her plan secret until showtime). What a fun Easter egg! I'm sure someone must have noticed it before, but my mind is blown.
