CSR might be the only K-pop group where age was actually significant to the group’s founding. A2Z Entertainment created CSR as a group where, by the traditional Korean age system (which is a little different than the method by which age is typically calculated), the entire group debuted at the age of 17. The name CSR stands for “Cheotsarang” (첫사랑), meaning “First Love,” and their debut mini album, Sequence : 7272, addressed the concept of falling in love for the first time at age 17. CSR officially debuted on July 27, 2022 with the lead single “첫사랑 (Pop? Pop!)” on Sequence : 7272. And if you really want to get exact about how old the CSR members are now, here is the current age and birthday for Geumhee, Sihyeon, Seoyeon, Yuna, Duna, Sua, and Yeham.
How Old Explained: Age & Birthday for the CSR Members
- Geumhee is 18 years old and was born on March 4, 2005.
- Sihyeon is 18 years old and was born on March 12, 2005.
- Seoyeon is 18 years old and was born on March 26, 2005.
- Yuna is 18 years old and was born on April 23, 2005.
- Duna is 18 years old and was born on April 28, 2005.
- Sua is 18 years old and was born on July 23, 2005.
- Yeham is 18 years old and was born on October 7, 2005.
With this information, we can see that, at the time that CSR debuted in July 2022, every member of the group was 17 years old except for Yeham, who was 16. That of course makes Yeham the maknae, meaning she is the youngest member of the group. CSR is the only group to ever debut with this unique age distribution and with nearly all members aged 17.
Of course, in a group with birthdays this close, seniority becomes less of an issue, and so it is less surprising that the eldest member, Geumhee, is not the leader. Rather, Sua is the leader of CSR, and there is only around four months of difference in age between her and Geumhee. However, it is still notably unusual for the second youngest member of a large group to be its leader!

Between current age and birthday, you now know exactly how old the CSR members Geumhee, Sihyeon, Seoyeon, Yuna, Duna, Sua, and Yeham actually are. With their pure image and bright music, they are often compared to GFriend, and CSR are indeed big fans of GFriend. GFriend is of course a good bit older than CSR though, so if you’re curious, you can check out how old the GFriend (and Viviz by extension) members are next!
