Lee Yun Sang is a South Korean singer, dancer, former member of ASTIN (아스틴), AWEEK (어위크), IB147 (아이비147), and current member of L5ST (로스트). He is enrolled in the Practical Dance program at Sejong University Lifelong Education Center.

He made his debut in March 2019 (under the stage name Mir) as ASTIN's lead rapper, sub-vocalist, and dancer with their first EP, "Mirror, Mirror". However, after the promotions ended, the group went on an indefinite hiatus as Kingtop Entertainment faced financial problems. By June 2019, he decided to leave the agency and the group.

He switched agencies and re-debuted (now using the stage name Logan) in November 2019 as AWEEK's lead vocalist, lead dancer, and maknae with their first mini-album, "The Birth of Seven". The group was managed by Illusion Entertainment (일루젼 엔터테인먼트) in South Korea and Oneworld Entertainment in Japan but, neither agency could do a proper job and it went on hiatus since mid-2020. AWEEK officially disbanded in mid-2023.

He joined HnA Entertainment and re-debuted (now using his real name) in February 2023 as part of IB147 with their first single album, "Overshock". The group later released a second single album before becoming inactive. The agency has not made an official announcement regarding the group's status, but it is implied they have disbanded since early 2024.

He re-debuted once again in September 2024 as L5ST's leader and main rapper with their first single album, "Only One". They are managed by Macaroni Media.
