One over Star! Hello, we are I.ONE!


I.ONE (아이원) was a pre-debut three-member girl group under LPA Entertainment. They were originally supposed to debut sometime in 2017, as was announced by the group (A-Young, Hayan, and Narin) on April 27, 2017, during their first showcase held at Gangnam Station.[1][2]

However, due to some line-up changes, the group re-scheduled their plans to debut in 2018. They were also planning to debut with four members instead of three.[3] Their profile on the website has not been updated ever since.

Around April 2019, all of the group's social media were deleted, making it believed they had disbanded. This was also the last month they were in the idol group brand ranking.[4]
