Choi Chang Min, known professionally as Sian, is a South Korean singer, dancer and former member of TFN (티에프엔, previously known as T1419). He graduated from Hanlim Entertainment Arts High School and is enrolled in the Broadcasting Entertainment program at Global Cyber University.

Sian officially debuted in 2021 as the group's main vocalist 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," also releasing a single in Spanish and joining the Weverse platform. In October 2022, the group was officially renamed TFN (short for "Try for New"). A few days later, it was announced that he would go on hiatus due to sensorineural hearing loss which caused him dizziness and headaches. He came back some months later, but in June 2023, he went a second hiatus for the same reason.

TFN's disbandment was announced in February 2024.
