Jiyoon opened up about 4minute, the group's former members, and more to Ten Asia. 

First, she revealed that she still keeps in contact with her former 4minute members, saying, "The members helped me a lot in preparing my album. Whenever I expressed concern, they gave me practical advice. They knew what I need to do when I ran into trouble since we've promoted together in the past."

Jiyoon also claimed that their relationship improved after the group's disbandment. She explained, "We went through a tough time together. Our relationship became stronger. We had to tightly come together, and we also became closer while sharing our pain."

As for the many rumors about the group, Jiyoon said, "It's frustrating. We heard about ourselves through the news, and we couldn't explain everything. It was upsetting. We wanted to tell everything, but people just assumed things, and that was upsetting." She continued, "We wanted to say that our members are doing well, but rather than speaking, I think it'll be better for us to show through music or promotions." 

Meanwhile, Jiyoon is making her debut with 'Day AND Night' and title track "I am the Sun".
