Today’s Palco Mundo stage filled with the heat of STAY, I won't forget the cheers! 🎸⚡

Why Koreans care

The title’s 스테이 (STAY, Stray Kids’ fandom name) addresses the audience as part of the group’s own fan community. The hashtag “You Make Stray Kids Stay” extends the wordplay: STAY is both the fandom name and the English verb tied to Stray Kids’ identity.

In the Korean comments

All 12 sampled Korean-language comments are warm, but two give useful off-site perspectives: one reads, in translation, “Although I couldn’t go in person, I watched the whole thing on TV,” while another asks the group to return and says, “Brazil loves you.”

What the words mean

꽉 채워준 (kkwak chaewojun, filled completely) describes STAY’s energy and cheers filling the stage; it does not by itself claim that every audience seat was occupied. It is affectionate, emphatic concert-thank-you language.
