In the Korean comments

The comments show this clip landing inside Korean baseball fandom, not just K-pop fandom. One commenter writes, in translation, "Eunchae-ya, our Nuri dances as well as Cheolung-i does... I'm so jealous of the team Eunchae roots for" — treating Eunchae's mascot cameo as a point of pride tied to which baseball club she supports. Another, identifying as a fan of a rival team, writes in translation, "As an LG fan... I'm in tears" — a comically exaggerated reaction to a rival team's mascot getting the spotlight, not literal grief. A third comment reads, in translation, "Seriously, a Doosan newbie, lol," using 두린이 (durin-i), literally "Doosan kid" — casual slang for someone who has only recently become a Doosan Bears fan.

What the words mean

두린이 (durin-i) reads literally as "Doosan child," but it's baseball-fan slang for a new or inexperienced Doosan Bears supporter — casual and self-deprecating, used the way a fan might jokingly call themselves a rookie.
