2022–2023: Departure from Star Empire Entertainment, solo debut with KH Company, and Sing Again 3
Star Empire made an announcement on January 4, 2022, stating that the members of Imfact, including Jeup, collectively settled upon the decision to not renew their contracts with the company. No official statement has been released regarding the status of Imfact as a group. Therefore, Jeup's position as a member remains unchanged as of September 2024.
In April 2022, Jeup signed with KH Company as a soloist under the stage name of Seoul. He released his debut digital single "Daystar" the same year on October 3.

On January 25, 2023, Jeup notified fans of his decision to change his stage name from Seoul to his birth name, Park Je-up. This change was prompted by challenges in discoverability because of the association with South Korea's capital. Jeup subsequently released digital single "Day by Day" in collaboration with singer U Sung-eun on February 25.
In late 2023, Jeup appeared as a contestant in the third season of JTBC's reality television show Sing Again. He was eliminated in the fourth episode, having passed the first round but not the second.
