On June 2 episode of SBS' television show 'Fantastic Family', Yoon Seul-gi made a special appearance.
While talking to the hosts, Yoon Seul-gi said about Yoon Ji Sung, "I was able to become a home shopping host all thanks to my brother. When I was going to private institutes for my lessons in Seoul, he financially supported me and provided food and a place to stay. Thanks to all that, I was able to slowly build up my skills as a good home shopping host."

He continued, "It was a semi-basement room, where it was super hot in the summer, and super cold in the winter. It was also too small for two adults to lie down. So, one of us used a bed, while the other one lied on the floor with their legs in the bathroom. As the bathroom floor was icy cold in the winter, we would heat it up using warm water, then put our legs on it once it warmed up well."

She resumed, "There were times when my brother didn't earn any money, because he was a trainee. I did though, with my part-time job. We would get some fried chicken to eat on my payday; that was the most luxurious thing we did back then."
Yoon Ji Sung responded, "Life wasn't easy then. I honestly wouldn't have been able to go through the hardships by myself. It would've been impossible for me to live like that for such a long time if she wasn't there with me.

Wanna One kicked off the group's promotion in August 2017, then officially wrapped it up with their final concert 'Therefore' in January 2019.
After Wanna One's disbandment, Yoon Ji Sung went solo, and also has begun his career as a stage actor.
