Thank you for coming today, STAY! Let's meet again!

Why Koreans care

The title addresses the audience directly as 스테이 (Stay), the name of Stray Kids' fandom. The English line in the description uses the capitalized form "STAY". The official links promote "THIS & THAT" and two remix releases, "This Remixes" and "That Remixes". The description does not say what footage the video contains or which performance it comes from.

In the Korean comments

Several of these Korean-language comments are birthday messages for the member Seungmin. One long comment reads, in translation, "Seungmin, happy birthday! Thank you for bringing happiness to so many people with your warm smile and wonderful voice. I feel your sincerity and effort every time you sing." It ends by thanking him "for being with us as Stray Kids' Seungmin". Another commenter asks that Seungmin be told a friend of STAY sent birthday wishes. Two other comments praise the singing. One says it was really good when Seungmin sang, and another says that his voice is beautiful. A separate comment names "After You" as the commenter's current favorite song and says they hope to hear it live someday. It says the lyrics are beautiful.
