Nayeon's quick reflexes saved fellow TWICE member Momo from grave danger during a rehearsal for an open concert for which TWICE was on Jeju island. Undoubtedly very unfamiliar with the new stage, Momo may have become a little too engrossed in her choreography to notice that the stage ended and dipped down into the audience behind her, and she began stumbling toward a direct fall. Nayeon, noticing, jumped up from her part during the song and caught Momo, righting her fellow member and pulling her to the safety of the stage! 

Momo seemed shocked, then went on to thank Nayeon with an aegyo-filled back hug. Good thing the girls were only rehearsing, which gave Jihyo time to check up on the two!

You're a hero, Nayeon!
