, Choi modeled for Andar and Round Lab, Joy Gryson, Nature Republic and , as well as Swarovski, Sulwhasoo and Maybelline. She and the rest of the Single's Inferno 3'' cast modeled for
Dazed as the show was airing. After her rise to fame, a 2021 modeling experience with
Enhypen came to light. While on the program, she notably wore a
Rom&nd's lip tint which later won a 2023
Olive Young Award. She also maintained a workout routine five days a week of weight training, gym, yoga, and running, and kept a strict diet. After the show ended, she started a
YouTube channel that she originally intended to devote to
ASMR. Choi reunited with fellow ''Single's Inferno 3'' participant
Yu Si-eun to model for
Alice + Olivia after the show's finale, and her
outfit of the day looks were compared to castmate Cho Min-ji's. In June 2024, Dentiste selected her as the star of their new brand campaign, launching with two videos on Dentiste's YouTube channel. Later in 2024, she modeled for
lululemon before being selected as ambassador for
F&F's Sergio Tacchini brand for the rest of the year. She also modeled for
Olay,
Fila, and
Skin Food. At the end of 2024, she was featured in volume 33 of Olive Young's
My Precious editorial. After Choi's appearance on
Game of Blood 3, she was invited to the
Ganni Show at
Paris Fashion Week in early 2025, as well as the EENK show with ''Single's Inferno 4'' participant Chung You-jin, a fellow Ewha Women's University alumna. Chung and her castmate Kook Dong-ho collaborated with Choi on an avatar blind date for
Esquire, during which she revealed that her
Myers-Briggs Type Indicator was ENFP. A later social media post from Choi attracted media attention, and comment from Chung herself. Choi also modeled for
Max Mara in Granada and attended the grand launch event for the item she modeled. She later modeled for
Calvin Klein and was invited as Korea's representative to
Longchamp's global influencer event in London, before reuniting with Max Mara at their runway collection in Milan and attending No.21's spring show. As of early 2026, she worked as a data scientist consultant, and was later selected to participate in HK inno.N's Zero Sugar Campaign due to showing her "confident charm" in dating entertainment, before being selected as a new brand model for
Allergan's Skinvive and Juvéderm due to her unique natural and healthy charm. Choi's candid appearances also continued to attract media attention, as in
Lisbon, when her past media appearances were noted along with her contemporary natural expression and feminine silhouette. ==Philanthropy==
