TWICE Jeongyeon warmed fans' hearts after she revealed the reason for joining the group's comeback promotion despite her health condition.

The reason TWICE Jeongyeon made her comeback despite a neck injury (herniated disc in the neck) is being re-examined. On YouTube channel ODG, TWICE members Jihyo, Tzuyu, and Jeongyeon appeared as special guests, and in the video, their career was examined by high school sophomores.

In the uploaded clip, Jeongyeon opened up about her neck injury and unveiled why she decided to participate in TWICE comeback despite it.

TWICE Jeongyeon Hospitalized Ahead of 'MORE & MORE' Comeback, Reason She Still Joined Group's Promotion

On the broadcast, Jeongyeon watched their "MORE & MORE" stage together with a high school student and narrated the behind-the-scenes story of her performance.

"I had a neck disc at that time. I was hospitalized a week before the comeback. So I think a lot about this (when I see the stage)," and revealed the reason for suppressing her pain to join TWICE's stages.

Jeongyeon didn't want to worry her fans about her condition. In fact, when the female star revealed her neck injury in 2020, she left this anecdote at that time through V Live.

"I had a neck disc surgery a week before the comeback. I didn't want to tell ONCE (TWICE fandom) because I didn't want to show my pain."

Jeongyeon also confessed stories about her previous comebacks including "I CAN'T STOP ME" and "Alcohol-Free."

"I stopped working on 'I CAN'T STOP ME' because of health problems. So when we made a comeback after a few months with 'Alcohol-Free,' I was as nervous as I was when I debuted," the female star said.

"But I can do it when I go up to the stage. Strangely, my expression came out again. I think I've lived really hard so far after watching all the stages. I'm also proud of giving happiness and joy to many people through music," Jeongyeon happily added.
