In a recent interview with DongA, YoonA shared, "It's been over 10 years since Girls' Generation debuted, so our attitudes have changed. On variety shows, there was a tendency to hesitate, thinking, 'Viewers might not like this,' but after gaining experience on varieties, we've gotten a lot better."

She also referred to their latest appearance on 'Knowing Brothers', saying, "Everything we said on 'Knowing Brothers' were things we talked about in waiting rooms before, so none of us felt bad about it. The Girls' Generation members know each other's personalities well now. That's why it was so fun watching our reactions to the ad-libs we made on 'Knowing Brothers'."

YoonA revealed how her fellow members cheered on her recent drama 'The King in Love' as well. She said, "When 'The King in Love' was airing, the Girls' Generation members all watched it. Hyoyeon unnie in particular was definitely a fan of Wang Won (played by Siwan), but after a certain episode, she started saying Wang Lin (played by Hong Jong Hyung) was cool too."
