Thank you U.S 🇺🇸 You just made my night 💫

In the Korean comments

One comment abbreviates “Make My Night” as 메.마.나 (me-ma-na, the phrase’s Korean syllables) and calls Hong Eunchae its “promotions team leader.” Another reads, in translation, “Thank you, LE SSERAFIM, for making my night in Chicago on October 2,” echoing the lyric back to the group.

What the words mean

한 줄기 빛 (han julgi bit, literally “a ray of light”) is not literal here. It casually and affectionately calls the clip a welcome bright spot during the difficult return to work after a holiday.
