The 8-member group Stray Kids was formed in 2017 in the reality show of the same name under JYP Entertainment. On March 25, 2018, Stray Kids made their debut with the mini album "I Am Not", but with 9 members. Before their official debut, they already released a mini album called "Mixtape" and the digital single "Hellevator", because the guys already showed their distinct talent in composing their own songs. The time before their debut was also very hard and tugged at the member's nerves. Felix and Lee Know were elimated from the reality show and had no chance to debut, but in the last episode both got another chance and actually made it into the group, also to the delight of many fans.

Already one year after their debut they released 3 mini albums and this closed the album series "I AM". After that followed the "Clé" series, which has a connection with the previous albums. If you look closely at the music videos from these eras, you can also see this.

On October 27, 2019, JYP announced that Woojin was leaving for personal reasons. Since then, Stray Kids were 8 members and with ever-increasing success. The following albums let the fanbase of Stray Kids grow more and more, so that they quickly already belonged to the big ones. Around the world, the guys fill numerous locations, which were sold out in record time, including 2019 in Berlin.

In 2021, Stray Kids were canidates of the show "Kingdom: The Legendary War", where several groups have to prove their talent in different performances. Although Hyunjin was not there due to a bullying scandal from their school days, Stray Kids took the win. The population for them grows more and more and this is what they deserve after thier hard work!
