Choi Ju Hwan, known professionally as ON, is a South Korean singer, dancer and former member of TFN (티에프엔; previously known as T1419).

He officially debuted in 2021 as the group's rapper, visual, vocalist and face of the group with their 1st single album, "Before Sunrise Part 1." The group had released a pre-debut single "Dracula" a few months earlier, but MLD Entertainment decided to wait a little longer before debuting them in South Korea.

One year later, the group debuted in Japan with their 1st mini album, "Our Teen: Blue Side," and also released a single in Spanish and joined the Weverse platform. In October 2022, the group was officially renamed TFN (short for "Try for New").

TFN's disbandment was announced in February 2024.
