On March 13, TWICE's Mina and Sana appeared on KBS Cool FM's 'Haze's Raise the Volume' to introduce their new mini-album 'Ready to Be,' which was released on March 10.

From the beginning of the show, Mina and Sana talked about their new album and the no-makeup concept. Sana explained, "First, the way we came to this concept is Jeongyeon told the company and said she always to a no-makeup concept. So, we thought it would be good if it was planned out well." Haze replied, "I watched that video so many times. That no-makeup concept was so beautiful."

The three K-pop artists talked about other topics other than TWICE's new album, such as the types of perfumes they like.

Both Sana and Mina shared that they like perfumes. Haze shared, "That's why when you came in you said to me, 'you smell nice'." Sana continued, "Yeah something smelled nice when I walked in," and laughed.

Haze read a fan's question asking about Sana and Mina's perfumed preferences, and Sana shared that she likes sweet-smelling perfumes. Mina shared that the scent she's been using the most was a cherry scent.

During the show, Haze asked Mina, "Who is the celebrity friend that you hung out with most recently?" and Mina immediately replied, "Lisa?" and elaborated, "When we hang out we go out to eat a lot of yummy foods." Haze continued, "And you talk and spend comfortable time together." And Minah responded, "That's right, that's right."
