Yoon Jeonghan Lost His Earphones

In the Korean comments

One top comment supplies the gag missing from the sparse captions, reading in translation: “Why would Yoon Jeonghan’s earphones be inside his pants?” Another asks why he even shakes out a shoe while searching.

What the words mean

“미쳤나봐” (michyeonnabwa, literally “must be crazy”) is not a serious judgment here. Commenters use it as a casual, exaggerated reaction meaning roughly “this is absurd” or “I can’t believe him.”
