Looks Can Kill

In the Korean comments

One comment reads, in translation, “What are those pretty, bright-red nails Leeseo has?” Another calls her “Red Leeseo” and jokes that a hero would collapse from an explosion of cuteness, not fear.

What the words mean

괜히 이서겠어 (gwaenhi Iseogesseo, literally “Would she be Leeseo for no reason?”) really means “There’s a reason she’s Leeseo” or simply “Of course she’s Leeseo.” It is casual, playful praise framed as a rhetorical question.
