Ichillin' (; stylized as ICHILLIN') is a South Korean girl group formed by KM Entertainment. The group is currently composed of seven members: Jiyoon, E.Ji, Jackie, Joonie, Chaerin, Yeju and Chowon. Former member Sohee left the group in July 2022. The group made their debut on September 8, 2021, with the digital single "Got'Ya".
Name
The group name Ichillin' is a compound of the words Aisling, which has the meaning of dream and vision, and Chillin, which has the meaning of relaxing or coolness. This is made in hopes of encouraging the listeners of their music to dream and relax.
The official fan club name of Ichillin' is "Willing", which was announced on December 10, 2021 after a poll between 7 candidates that each of the members have picked. It has the meaning of ardent fans who enthusiastically like the group.
History 2021: Debut with Got'Ya and comeback with Fresh Ichillin' was to debut on August 25, 2021, but it was delayed in order to show more completeness in the group through improvements on the album. The group subsequently made their debut with their first digital single "Got'Ya" on September 8, 2021, two weeks after the supposed debut date.
The group then had their first comeback on November 11 the same year with their second digital single "Fresh".
