Once You Fight, It Lasts Two Days: IriOnz

In the Korean comments

The joke lands because specific comments reject the title’s premise. One top comment reads, in translation, “The pairing least likely to fight,” while another says, “They seem like they’d make up in under a minute even if they did fight.” A third adds, “You said you’ve never fought.”

What the words mean

한 번 싸우면 이틀은 가는 (han beon ssaumyeon iteureun ganeun) literally says that once a fight starts, it “goes for two days.” Here, 가다 (gada, to go) means the conflict or bad feelings last that long, not that they fight continuously for 48 hours; the title uses casual, playful exaggeration.
