Choi Chi Hoon is a South Korean singer, dancer, producer, former member of TO1 (티오원, formerly known as TOO) and member of UMZ (우주멸망작전). He graduated from Seohae High School.

He participated in Mnet's survival show, "World Klass" and was selected as part of the show's project group. He made his debut in April 2020 as TOO's rapper, vocalist and producer with their first mini-album, "Reason for Being: 仁 (Benevolence)".

The group was originally represented by WAKEONE (웨이크원) and n.CH Entertainment (n.CH엔터테인먼트). However, in March 2021, n.CH decided not continue in this joint venture leaving WAKEONE as the sole agency managing the group. They decided to rebrand and changed the group's name to TO1.

In April 2022, and just one month before the group on hiatus, he reached an agreement with WAKEONE and his contract was cancelled. He left the group a few days later.

He is part of a producing team called CUROHAKO.

In 2026, he was announced as a member of the South Korean band "UMZ".
