Lee Jong Hoo

Sometime in late 2023, Jong Hoo became one of the founding members of the boy band DIRTY SHOE. In early January 2024, DIRTY SHOE began publishing song demos on their SoundCloud account. They had published a total of 15 song demos in 2024, of which, the self-titled song "Dirty Shoe" became their debut digital single and was released on May 2, 2024, marking Jong Hoo's debut with the band.

In October 2024, Jong Hoo appeared as a contestant in TV Chosun's music survival show Campus GAYO in which he competed as the vocalist for DIRTY SHOE. Eventually, DIRTY SHOE finished the show as the second place winners. As a result, DIRTY SHOE (and Jong Hoo) signed a contract with Jellyfish Entertainment.
