ASTRO‘s JinJin revealed the story behind Moonbin‘s sexy and fierce ending fairy for their “ONE” stage at SBS Inkigayo during his latest live broadcast.

Turns out during their recording, Moonbin felt pressured to do something special as the ending fairy because directors onsite told him “We trust you!”

But Moonbin wasn’t satisfied with his first attempt, and the directors asked him to give it another shot.

JinJin shared that he had to hold back his laughter at Moonbin’s fierce ending fairy, and that it was like a “try not to laugh challenge for everyone.”
