From SKZ’s early steps and first entries on the Billboard charts to becoming an international sensation, Stray Kids’ career path is as thrilling as their music. When you think you know how the Stray Kids story goes, the group will surprise with a sonic pivot or unexpected move. 

This is Bang Chan, Lee Know, Changbin, Hyunjin, Han, Felix, Seungmin, and I.N’s story together so far.

August 2017: JYP Entertainment announces plans to launch a new male group through a reality singing competition show. It’s the K-pop label’s first new boy band since 2014, and JYP’s latest reality show after the successful creation of the girl group TWICE through their 2015 show Sixteen.
