Kim Yo-han first became known to the public in 2019 as the winner of Mnet’s hit idol audition show “Produce X 101.” He debuted as a member of the project boy band X1, consisting of the show’s 11 finalists. X1’s debut EP “Quantum Leap,” sold over 524,000 copies and became the first K-pop album by a debuting artist to sell more than half a million copies. After X1 disbanded in early 2020, Yohan started his solo career that August with the digital single “No More,” and also went into acting. He went on to become a member of boy band WEi and is still active as a solo singer.
