SEE ALSO: Kang Daniel unveils emotional pop-rock track ‘Mess’ special video

On 'Problematic Men' this week, the producer who created the very popular song "Pick Me" for the second season of 'Produce 101' appeared on the show. He was asked if there were any contestants that caught his eyes from the start of the survival program. 

Ryan Jhun answered, "There were trainees and singers whom I knew personally before the show began. But from those who I met for the first time, Lee Dae Hwi and Kang Daniel caught my eyes. There was also one other member that I wanted to keep a close eye on in particular and purposely kept him in the recording room longer because I wanted to see what kind of a person he is. He is Ong Seong Wu. I was interested because of his singing style but it also seemed as if he knew how to actually sing - he felt like an actor rather than a singer but apparently he was doing that as well. He's talented in many areas."

Did these three members catch your eyes right from the beginning as well?
