When Jeongyeon was asked by host Kang Ho Dong what she would want another member to fix about themselves, she quickly explained that Nayeon has a habit of hitting the person next to her when she laughs.
Even Chaeyoung interjected that it hurts when she hits them.
That was when Heechul recalled that during one of their first appearances, Nayeon was paired up with Sugeun and she hit him so much during that episode that he joked about shrinking by 3 cm (almost 2 inches).
Nayeon acknowledged that she knows she shouldn’t do that but it had already become a habit for her.
We wonder how her slapping habit is nowadays.
