Lee Seo Yeon, known simply as Seoyeon, is a South Korean singer, dancer and member of FROMIS_9. She attended Seoul Performing Arts High School but dropped out. Before debuting, she was a trainee at YG Entertainment and was part of a trainee group called "Future 2NE1", which included Billlie's Moon Su Ah. However, the members began switching agencies and debut plans, originally scheduled for 2016, were postponed and eventually cancelled.

In 2017, she participated in the singing survival show "Idol School", where she ranked in 7th place and earned a spot in the group. She officially debuted in 2018 as FROMIS_9's main rapper and vocalist with their 1st EP, "To. Heart", which landed in 4th place on the Gaon Album Chart.

In September 2018, Stone Music Entertainment confirmed that the group would now be managed by Off the Record Entertainment, a new label established by Stone Music to manage this group and Iz*One, with Pledis Entertainment in charge of the creative direction and the production of the group's music. The move was heavily criticized by fans as they felt the group was neglected in terms of promotions and releases compared to Iz*One. That same year, she made her acting debut with a role in the web series "Welcome to Heal Inn".

In 2020, she took time off after suffering a leg injury while practicing.

In 2021, the group fully transferred to Pledis after Off the Record re-organized. This generated more criticism as Pledis has a history of mismanaging girl groups and hindering their development. In late 2022, she took a break due to health concerns but has fully recovered as she was part of the group's 1st studio album, "Unlock My World", released in June 2023.
