Im Chang-kyun (; born January 26, 1996), known by the stage name I.M or mononymously as Changkyun, is a South Korean rapper, singer, and songwriter. He debuted in the South Korean group Monsta X through Mnet's survival show, "No.Mercy" in 2015. He made his solo debut with the EP "Duality" in 2021.
Career.
Early life and debut.
I.M was born on January 26, 1996 Suwon, Gyeonggi-do, South Korea, although he cites the Gwangsan-gu of Gwangju as his hometown. He spent most of his early years living abroad because of his father's work as a scientist, including living in Boston, Massachusetts, where he gained fluency in English while his father worked at Harvard University.
In 2013 and 2014, I.M was a part of the boy band Nu'bility, under Special K Entertainment. The group never officially debuted, despite holding several events and performances.
I.M was a late addition to Mnet's survival show, "No.Mercy", becoming the thirteenth competitor. Despite his late addition, he was one of the seven contestants chosen to debut in Starship Entertainment's new hip-hop boy group, Monsta X.
2015–present: Monsta X and solo work.
I.M debuted with Monsta X with the 2015 release of their first EP, "Trespass," on which he has five writing credits.
In 2016, I.M released his first mixtape through Starship Entertainment's YouTube channel, titled "Who Am I?" and featuring Yeseo.
In 2019, I.M released his mixtape with the lead single "Horizon", which was a collaboration with the American artist ELHAE. He released "Scent" as the B-side of the single.
In February 2019, I.M narrated an audiobook, Oscar Wilde's "The Happy Prince", released through Naver's Audioclip. Later that year, he narrated two audiobooks alongside groupmate Shownu, also released through Naver's Audioclip.
In 2020, I.M collaborated with ELHAE again, releasing the single "Need to Know". I.M also made his first solo appearance on a talk show, on "Talk Talk Information Brunch". 
In January 2021, I.M announced the solo work he had been preparing in 2020 would be released as his first solo album, with an intended release later in 2021. His first official solo song release, rather than a mixtape release, was announced to be an extended play titled "Duality", released on February 19, with the lead single "God Damn". I.M was praised for showing a wider diversity of skill with the EP, with a noted difference in rap-style from his work in Monsta X as well as showcasing his abilities as a vocalist, songwriter, and composer. All five songs from the album charted on "Billboard"'s World Digital Song Sales chart for the week of March 6, and therefore he occupied a fifth of the positions on the chart in that week.
Songwriting.
I.M has writing credits on the majority of Monsta X's discography as he writes his rap verses for Monsta X. As of his most recent solo work and Monsta X's release of "Fatal Love", he has 99 writing and producing credits registered with the Korea Music Copyright Association (KOMCA). For Monsta X's album "Fatal Love", the song "Night View", on which he was both a writer and composer for, ranked number thirteen on the "Billboard" World Digital Song Sales chart. In addition to Monsta X's discography, he writes and produces for his solo work and collaborative projects.
