TDOONG's Crossing EP.03 Highlight #2

In the Korean comments

One comment reads, in translation, “Happy ONCE Day!” Another playfully turns the cake into a sign of closeness: “We’re close enough to share cake, you know.”

What the words mean

The auto-captions show 원수 (wonsu, enemy) in the birthday song and greeting, but the context strongly indicates 원스 (ONCE, TWICE’s fandom). The comments’ “Happy ONCE Day!” and “TWICE and ONCE, let’s stay together forever” make clear that this is a birthday message for ONCE, not an address to “enemies.”
