Lee Chang Sun is a South Korean singer, dancer, model, former member of 24K (투포케이, now re-branded as 24K+) and current member of TAN (티에이엔). He graduated from Kookje University with an associate's degree in Practical Dance.

He made his debut in August 2016 when he was added to 24K after the group had debuted in 2012 but underwent several lineup changes. He joined as the main dancer and vocalist with their digital single, "Still 24K". He will become the group's leader in January 2019 when Corbyn (formerly known as Cory) left the group.

In June 2021, he was part of the digital single "Welcome to the Mainstreet", which ended up being his last collaboration for 24K. Later that year, he entered the singing survival show "Extreme Debut: Wild Idol" and finished in 1st place, earning a spot in a new project group called TAN.

He signed a two and a half year contract with Think Entertainment (생각엔터테인먼트) and re-debuted in March 2022 with their 1st mini-album "1TAN" as the leader, main dancer and sub-vocalist. In September 2023, he officially announced his departure from 24K to focus exclusively on TAN.

However, Think Entertainment became embroiled in several controversies and all members ended their contracts in June 2024. The group has not disbanded but is now on an indefinite hiatus while some members fulfill their mandatory military service and others focus on other activities.
