Looks Can Kill

In the Korean comments

One comment calls this “대표 장신돌 멤버들 간의 만남” (daepyo jangsin-dol membereul gan-ui mannam, “a meeting between representative tall-idol members”). 장신돌 (jangsin-dol, tall idol) combines “tall person” with “idol,” making their height part of the pairing’s appeal.

What the words mean

In one comment, “내 최애 언니” (nae choe-ae eonni) does not mean “my favorite biological sister.” 최애 (choe-ae) is a fan’s top favorite, while 언니 (eonni) is an affectionate form of address used by a younger female speaker for an older woman; here, the commenter is excitedly calling Bang Jeemin her favorite idol.
