His Japanese debut in 2017 coincided with the launch of the Piece of BTOB project,[10][unreliable source?] which saw each BtoB member releasing solo digital singles during the group's promotional hiatus in the summer of 2017.

He started his career in musicals in 2017. He was cast in the musical adaptation of "Boys Over Flowers" as the lead, Goo Jun-pyo.[11] He also played a role in the Korean production of the musical "Napoleon" as Lucien, Napoleon's little brother.[12][13] Next, he was cast as the titular main character in the musical "Edgar Allan Poe".[14][unreliable source?]

The following year, he landed another leading role as Eddie Birdlace in "Dogfight".[15] His final musical project before military enlistment was "Iron Mask" where he undertook the dual leading role of King Louis XIV as well as his twin brother Philippe [16]

In December 2018, he released his first Korean solo EP titled Mark.[17] He considered it a gift to his fans before his enlistment in January 2019. He held his first solo concert, SPACE, on January 4, 5 and 6, 2019 at the Yes24 Live Hall in Gwangjin District, Seoul.[18][19]

On October 27, 2020, Cube announced that the currently active members of BtoB would form a unit called BtoB 4U consisting of Eunkwang, Minhyuk, Changsub and Peniel.[20] The unit debuted on November 16 with their first mini-album, Inside and title track "Show Your Love".[21]

Personal life

Health

Lee developed vocal cord nodules around the time of the recording of Mark, in late 2018.[35][36] In March 2024, Lee halted activities that involved singing due to his "poor throat condition".[37] Lee later revealed that he was diagnosed with vocal cord polyps, and had had three surgeries to correct it.[38][39][40][41]

Military service

He began his military duty by enlisting as an active duty soldier on January 14, 2019.[42] On July 24, Lee recorded a special single— a new theme song for the ROK Army alongside Shinee's Onew and Key, Exo's Xiumin, Infinite's Sungkyu, 2AM's Jo Kwon and Jinwoon, Yoon Ji-sung and actors Kim Minseok, and Lee Jae-kyoon.[43]

He was officially discharged on August 21, 2020, following the COVID-19 protocol.[44]

Philanthropy

On October 21, 2017, Lee Chang-sub visited his alma mater and delivered a scholarship of ₩10 million to his high school alma-mater, Samil Commercial High School. Changsub said, "I couldn't have imagined this when I was in school. It's an honor to be in a situation where I'm able to deliver this scholarship for the younger generation of students. I've been able to come this far thanks to my teachers and my school who helped me until the end when I was a student".[45]
