Yun Ah-sun

Yun began learning to skate in 2015. She placed eighth at the senior level at the 2020 South Korean Championships, and the won the silver medal the following year.[1] Due to the COVID-19 pandemic, the 2020–21 international junior season was not held, and Yun was therefore unable to compete on the Junior Grand Prix or at the World Junior Championships.[2][3]

With the resumption of international junior competition, Yun was scheduled to make her international debut on the Junior Grand Prix, competing back-to-back weeks in events both held in Courchevel. She placed fifth in both contests. Yun was sixth at the 2022 South Korean Championships.[1]

Due to her national result, Yun was named to South Korea's team for the 2022 World Junior Championships, but events would soon complicate the situation. Shortly after the conclusion of the 2022 Winter Olympics, Russia invaded Ukraine. As a result, the International Skating Union banned all Russian athletes from competing at ISU championships.[4] As Russian women had dominated international figure skating in recent years, this had a significant impact on the field.[5] Due to both the invasion and the Omicron variant, the World Junior Championships could not be held as scheduled in Sofia in early March, and were rescheduled for mid-April in Tallinn.[6] Yun placed third in the short program, 0.14 points ahead of American Lindsay Thorngren, winning a bronze small medal. She expressed disappointment at having lost levels on two spins, but said she was happy with the performance.[7] She was overtaken by Thorngren in the free skate, finishing in fourth place overall.[8]
