Lee Yeo Reum, known professionally as Gu Seul, is a South Korean singer, dancer, choreographer, and former member of GIRLS' ALERT (소녀주의보, later shortened to GsA). She graduated from Seoul Performing Arts High School.

She made her debut in May 2017 as GIRLS' ALERT's main dancer, main rapper, lead vocalist and maknae with their first digital single, "Dreamgirls". Unfortunately, Roots Entertainment (뿌리엔터테인먼트) faced severe financial distress during the COVID-19 pandemic, and after the departure of 2 members, the agency first opted to terminate the contracts of all the remaining members (including her) only to change their minds 3 days later. The group did not disband but has not released any new material since early 2019. They had a YouTube show during the pandemic. However, they officially disbanded in mid-2023.

She then became part of the dance crew DEEP N DAP (딥앤댑) and remains under Roots representation.
