Seven O'Clock (Korean: 세븐어클락; RR: Sebeun-eoklaek) was a South Korean boy band formed in 2017 under Staro Entertainment and KDH Entertainment. The group debuted on March 16, 2017, with their first mini album Butterfly Effect and the lead single "Echo," marking their entry into the competitive K-pop scene with a focus on vocal harmonies and dynamic choreography. Initially consisting of six members—A-Day, Vaan, Hyun, Young Hoon, Jeong Gyu, and Tae Young—the lineup later expanded and underwent several changes, including stage name changes (A-Day to Hangyeom, Young Hoon to 2Soul), the departure of Vaan in 2018, and the addition of new members such as Andy and Rui, before stabilizing at seven members toward the end of their career. Throughout their four-year run, Seven O'Clock released notable works such as the 2018 mini album #7 featuring the title track "Nothing Better," their first release under the newly signed agency Forest Network after departing from their original labels. The group continued with comebacks including the 2019 single "Get Away" and the 2020 mini album , showcasing evolving musical styles from pop-rock influences to more introspective themes, though they remained relatively underrated in the industry.

Pre-debut activities
