Kang Du Na is a South Korean singer, dancer, and member of CSR (첫사랑). She dropped out of high school but later passed the High School Graduation Certification Examination. She is enrolled in the Acting program at Baekseok Arts University.

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 July 2023, she became the new leader as they decided to have a rotating leadership position that was supposed to change every anniversary (however, it did not change in 2024). 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".
