Ahn Seo Yeon is a South Korean singer, dancer, and member of CSR (첫사랑). She graduated from Seomun Girls' High School.

The group was planned since 2019 by Isam Media (이삼미디어; formerly known as J Planet Entertainment). However, the lineup kept constantly changing, and by early 2022, it still had not debuted. Ultimately, the agency decided to transfer management control to Pop Music (팝뮤직) a few weeks before the group was launched.

She made her debut in July 2022 as part of CSR with the EP "Sequence: 7272". At the time of their debut, they became the only group in South Korea with members who were of the same age (17 years old).

In December 2023, she and 3 other members went to Thailand and appeared as contestants in the singing survival show "Produce Camp Asia: Thailand" but were not successful.

In July 2024, they debuted in Japan with the EP "L'Heure Bleue".
