Wanna One debuted in 2017 after the members were selected through the popular idol survival program 'Produce 101.' They might have been the most successful group to be produced by the Mnet survival show.

The group released various albums together before the contract was over after about two years. During that time, they set multiple records and received immense love from fans from all over the world.

Now, the members are all successfully promoting as solo artists or with their respective idol groups. Recently, the younger line of Wanna One is garnering attention as they have grown up over the years after their promotion with Wanna One.

Members Park Ji Hoon, Park Woo Jin, Bae Jin Young, Lee Dae Hwi, and Lai Kuan Lin were all in their teens when they debuted with Wanna One. These Youngins are now in their 20s, fully radiating a mature vibe.
