ICHILLIN' J showcased explosive chemistry among members on their self-produced YouTube content 'Hadahada Unit Kkaji Handa' (roughly, 'We Even Do It as a Unit').

In the recently released new episode, ICHILLIN' J — composed of Eiji, Jooni, and Yeju — traveled through Incheon's old alleys, used bookstores, and record shops, enjoying a trip full of retro charm.

The members spent time picking out and recommending books suited to one another, displaying their natural and close-knit chemistry. In particular, at the used bookstore, Yeju recommended a book to Jooni and joked, "Don't you have ADHD?" turning the scene into a sea of laughter. The members burst out laughing at the unexpected reason for the recommendation, which was a humorous exchange unrelated to any actual diagnosis. This kind of communication, possible only among members with deep friendships, showed off ICHILLIN' J's unique atmosphere.

Previously, ICHILLIN' J visited various locations such as Dongmyo, Daerim-dong, and a zoo in earlier episodes, displaying each member's personality and wit. In this Incheon episode as well, they heightened the fun of the content with their unfiltered conversations and unpredictable banter.

Meanwhile, ICHILLIN' debuted in 2021 with the digital single 'GOT'YA' and has since released numerous albums including 'FRESH', 'MY TIME', 'Challenger', 'BITE ME', 'DEMIGOD', and 'Prequel'. ICHILLIN' J officially began their unit activities with the release of the digital single 'Look At Me!' on September 2.

ICHILLIN' J's 'Hadahada Unit Kkaji Handa' can be watched on the group's official YouTube channel.
