YES i caught that too! theyre a specific trio that usually speaks krn when theyre together and fm has the tendency to default to it when promoting in kr so it was just interesting to me that fm was mostly talking in jpn while jju stuck with krn (although they were obv both mixing) but i was especially interested in how nc, who i feel tends to change over to krn like a switch especially if jju is talking to him first in krn, was purely replying in jpn (could be for a number of reasons: fm mostly leading the situation in jpn, heightened emotions = easily expressed in jpn since its arguably his most used verbal language, simply too put out to switch around etc)…anyway yeah…although wouldve preferred to see this language dynamic play out in any other situation that wasnt exploiting a visibly upset nc…
