The singer debuted with Girls' Generation in 2007, and she and her members just recently commemorated their 12th anniversary.

"As a girl group, our 10th anniversary was meaningful too, but even two years after that we still reach out for each other first and the atmosphere between us is so good. We cherish and respect each other so much that after we finished our 10th-anniversary album and we had our contract renewals coming up," she shared.

"We talked a lot about things such as asking each other what we wanted to do as the person Tiffany or the person YoonA. I wanted to go to acting school and try breaking into the U.S. market, and the members knew about that dream," she added.

Tiffany also revealed that they saw one another just a few days ago, and expressed that it's amazing they never change. For her, her members and her fans mean a lot to her.

"When I was doing an interview in America, I said that when I needed a family and a home, my members and music were there for me. In particular, my fans became my heart's home. They made a roof over my head and seem to be always protecting and cherishing me. Now in the opposite way, I want to protect them and do greater things for them. We have a warm relationship," she said.

Speaking of her acting auditions in the United States, Tiffany shared, "I'm steadily receiving scripts for auditions through my agency. There was an acting offer I received recently that was almost at the point of it being confirmed. I was happy over it like it was a college acceptance letter. The offer said, 'It's a role that would be a perfect fit for Tiffany,' but when I did the camera test they said I looked too young. A project that I believed was all set also fell through, and [there are] a lot of times when I feel frustrated."

Amidst these unpleasant situations, Tiffany still resorts to receiving comfort through music.

 "Music is still space where I work through my feelings," she revealed.

When asked what her aspirations are, she answered, "I want to become a timeless artist. Someone that won't be forgotten."

Tiffany added her statement with a revelation about her health.

"Actually, I have scoliosis, but I shared that for the first time after my promotions. That pain and weakness became strengths for me. I practiced twice as much as other people, took care of my health, and became a bit obsessed with fashion. It was to cover that up," she said. 

The interviewer told the singer that it seems quite a challenge to overcome the condition, but Tiffany showed strength.

"Rather than thinking 'I shouldn't let other people know about my pain,' I think the opposite, which is 'I'm who I am today because I've overcome scoliosis.' I also want to help young people with this if I can. There are a lot of people who are athletes, ballerinas, or models too that suffer because of scoliosis. But there isn't much awareness about this," she shared.

"When I was younger, I was told [by a doctor] that it seemed like I wouldn't be able to debut. I said then, 'No. I'm okay. I'm going to manage this and do better.' I adjusted everything about myself, like my body, my health, and even how I breathe and stand," she went on.
