Early career

Wi began figure skating in 2010 at the age of six. She moved to Gwacheon at the age of twelve to train under Choi Hyung-kyung.^[2][1] She is considered part of the second generation of "Yuna Kids," South Korean ladies who began skating after being inspired by 2010 Olympic Champion Yuna Kim.^[3]

Wi won the gold medal at the 2018 South Korean Junior Championships.^[1]

2018–2019 season

Wi made her junior international debut at the 2018 Asian Open Trophy in August, where she won the bronze medal behind teammate Lee Hae-in and American Gabriella Izzo. She then received her first Junior Grand Prix assignments, placing fourth at both 2018 JGP Czech Republic and 2018 JGP Armenia. Competing as a senior domestically for the first time, Wi placed sixth at the 2019 South Korean Championships and was not selected for the 2019 World Junior Championships team.^[1]

2019–2020 season

Wi opened the season by winning her first Junior Grand Prix medal, silver, at 2019 JGP France behind Kamila Valieva and ahead of Maiia Khromykh, both of Russia. Although Wi had to wear tape around her skates due her her skate boots had collapsing prior to the competition, she managed to become the fifth Korean lady to score above 190 points internationally at the event.^[4] Wi's medal set off a series of consecutive medal wins by Korean ladies on the 2019–20 Junior Grand Prix.^[3][2]

At her second event, 2019 JGP Poland, she finished fourth behind Alysa Liu, Viktoria Vasilieva, and Anastasia Tarakanova.^[5] She then competed at the 2019 Asian Open Trophy in November, winning gold by over 30 points ahead of teammate Ji Seo-yeon and Hong Kong's Hiu Yau Chow.^[1]

Wi finished fourth in the senior division at the 2020 South Korean Championships, behind You Young, Lee Hae-in, and Kim Ye-lim. As a result, she was named to the 2020 World Junior Championships team alongside Lee. At the 2020 World Junior Championships, Wi placed sixth in the short program after her flying sit spin was invalidated. She said: "It’s my first Junior Worlds, so I was very nervous today. I did no big mistakes, so I’m very satisfied."^[6] Wi improved to fifth in the free skate to finish sixth overall. Her placement, combined with Lee's, earned South Korea three spots for the next season.^[7]

2020–2021 season

With the COVID-19 pandemic greatly curtailing competitive opportunities for South Korean skaters, Wi competed first at the 2021 South Korean Championships, finishing fifth.^[8]

2021–2022 season

With the resumption of the regular international season, Wi was assigned to make her Grand Prix debut at the 2021 NHK Trophy, where she finished in ninth place.^[9]

Due to her national result, Wi 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.^[10] As Russian women had dominated international figure skating in recent years, this had a significant impact on the field.^[11] 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.^[12] Wi placed fifth in the short program.^[13] She was sixth in the free skate after falling on her final double Axel attempt but remained in fifth place overall.^[14]

2022–2023 season

Wi began the season with her Challenger series debut at the 2022 CS Nebelhorn Trophy. Although she had come down with the flu during the competition, she managed to win the silver medal after placing third in the short program and winning the free skate.

Given one Grand Prix assignment, Wi was assigned to compete at the 2022 NHK Trophy. Prior to the event, Wi contracted COVID-19, but was cleared on time for the competition. She would ultimately finish eighth.

She then closed her season with a ninth-place finish at the 2023 Korean Championships.^[1][2]

2023–2024 season

Wi came thirteenth at the 2023 CS Finlandia Trophy, her first competition of the season. On the Grand Prix, she was twelfth of twelve skaters at the 2023 Skate America and tenth at the 2023 NHK Trophy.^[1][15]

At the annual national ranking competition, Wi won the bronze medal and was selected to represent South Korea at the 2024 Four Continents Championships.^[16] She went on to compete at the 2024 South Korean Championships, where she finished in twelfth place.^[1]

At the Four Continents Championships in Shanghai, Wi came sixth in the short program. She was fifth in the free skate, her only mistake being a slight underrotation on a double toe loop, rising to fifth overall. Wi remarked "I wanted to do my best and I think I did."^[17]
