Lovelyz is currently appearing in Mnet's 'Queendom'. The process of preparing 'Queendom' and the solo album 'Over and Over' at the same time was not an easy task. 

"Because I had to prepare 'Queendom' together, I couldn't sleep and it was difficult. But I choose to enjoy if I couldn't avoid. I also tried a lot of things that I didn't do through 'Queendom.' Releasing a solo album was something new to me as I have never tried before. Park Bom doesn't have a mobile phone yet, so I contact her via iMessage, and during Chuseok, she texted, "Have a good holiday." 

"It may not show on air but honestly I don't like competition when shooting. I just try to be focused on my own work. These days, I try to perform as if I am watching others' performances." 

Kei drew much attention through her duet performance with Mamamoo. It was impressive to see Kei, who is usually shy, suggesting a duet straight to Hwasa.

"I have been in love with Hwasa for a long time. She is a singer who draws big pictures of songs as well as performances. I am usually an introvert to people, but this time I had a chance to go straight ahead. It was so fun to prepare. I desired so much to perform with her. I even brought Kimbab to her. She taught me a lot. I felt awkward at first as I have never tried her style. But she helped me a lot every time, so she was more of a mentor than a duet. It's an honor that I could perform with her on stage. "

The most highlighted stage of Lovelyz was 'Sixth Sense' of Brown Eyed Girls. Lovelyz transformed themselves from their usual beauty, surprised fans by changing them into strong sexy charisma.

"'Sixth Sense' came out of the group members' suggestion. I tend to stick to the image of Lovelyz, so I worried a lot. But the members wanted to do it. Members have unique talents, and I hope they have opportunities to be displayed. It is good for Lovelyz's to keep its present image now, but it's not bad either to show a new look through solo or contest. Fans loved to see the new concept, so we challenged ourselves. However, it turned out to be a success."

Due to the huge difference from the previous image, the popularity of ' Sixth Sense' was mixed with criticism. It would have been a bit of a difficult time for Lovelyz, who had rarely received criticism or negative comments.

"It's a pity that we've been criticized, but we don't have any regrets. We were so happy as we prepared ourselves. We also learned a lot from hearing those negative comments. I was grateful for this. I was not frustrated, but I thought we would have to keep the Lovelyz's color while listening to the criticism, I didn't get hurt by the critics, it's the right word to engrave in us and it's the words that have points. The members also told us to keep our colors to the end. I am thankful that they taught Lovelyz where to go. We have a pure and innocent image. Soul is 28 years old but still looks like a girl. So it seems that we can stick to the original lovely images of the group. I want to preserve this freshness of our group. That is why we keep making efforts. We take care of visual parts a lot as well as mental strength. The image we can create the best is being pure and lovely."

Through 'Queendom' Kei learned a challenging spirit.

"The first time when I competed, the solo album wasn't confirmed. Then, the solo album was confirmed. The duet stage had a lot of influence. This challenge strengthened my mind that it would be fun to try a musical transformation. I was afraid of the challenge. I tend to stick to the present image and I'm afraid of the adventure, but I could develop the spirit of challenge through 'Queendom'."

If so, what would have changed with the solo album?

"I had a deep feeling rather than learning something new through a solo album. I realized I have a lot of good people around me, and I wanted to do my best for them and keep keep the relationship with them. I have become more eager to continue singing. I think I have to learn one by one. I want to give it back the love that I have received. I think this album is a turning point for me. I came to know what I want to do. "
