Jeon Yu Jin, known professionally as Sat Byeol, is a South Korean singer, dancer, actress, and former member of GIRLS' ALERT (소녀주의보, later shortened to GsA) and PIXY (픽시). She graduated from Hanlim Multi-Arts High School.

She made her debut in May 2017 as GIRLS' ALERT's lead vocalist 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 did not release any new material since early 2019, and was supposed to re-launch as a trio. However, she was not included in the new project, so she decided to leave the group and the company.

After switching agencies, she re-debuted in February 2021 as PIXY's lead rapper and visual with their first digital single, "With My Wings". In August 2022, ALLART Entertainment (올라트엔터테인먼트) announced that she was leaving the group due to poor physical health and mental stress. Her contract was terminated.

She focused on her YouTube channel but later ended up re-signing with Roots Entertainment and made her debut as a solo artist in October 2024 with the digital single "Don't Know Why".
