Just recently, TWICE made a hot comeback with a new title song "What is Love?" produced by J.Y Park.

On the April 10 airing of SBS' 'One Night of TV Entertainment, the girls had an interview and were asked how J.Y. Park is different from other producers. Jungyeon replied, "It's unique how Park Jin Young PDnim makes each member sing the entire song."

Dahyun explained, "It's so he can divide the parts for us" and added, "Park Jin Young PDnim rates us during recording. For instance, he says, 'You are 98. We're 2 points away (from perfection) so let's do it one more time'."

Chaeyoung also said, "He creates an environment that helps me focus. He tells me, 'Imagine where you are'." On the other hand, Jungyeon playfully complained, "He tells me to portray emotions and sing as if I'm talking but how am I supposed to make it sound like I'm just talking when I'm singing?"
