Fun Facts

❥ Haerin was close to competing in the 2018 Pyeongchang Winter Olympics, but a bout of pneumonia two weeks before the qualifiers prevented her from participating. In 2019, she announced her retirement from competitive skating and took a year off to rest.
❥ Although she retired from professional ice skating at age 21, she still loves the sport and enjoys skating recreationally with friends and her group members.
❥ She previously ran a YouTube channel where she shared her ice-skating routines, Q&A sessions, and unboxing videos of gifts from fans. Her channel has been inactive since her retirement, with her last video being a heartfelt Q&A addressing her decision to step away from skating.
❥ Haerin auditioned for several entertainment companies, passing the auditions at JYP Entertainment, Jellyfish Entertainment, and Solstice Media. Ultimately, she chose Solstice Media, as she’s a big fan of Cherry Bomb and admired them since their pre-debut days.
❥ Known initially as the "Ice Princess" for her elegant aura and skating background, Haerin’s bright and outgoing personality led fans to call her "Sun Beam Haerin." She adores both nicknames and still uses them frequently.
❥ Haerin has three siblings: an older sister who’s a veterinarian, an older brother who’s a radio DJ, and a younger sister who’s currently a college student. She shares a close bond with all of them but is especially close to her brother, who shares her taste in music and inspired her passion for it.
❥ Besides being an idol, Haerin has a love for musical theater, with Phantom of the Opera as her all-time favorite musical. She often attends musicals with Emilia during her free time.

❥ She has been a brand partner with Oscar de la Renta since 2022.
❥ In late 2023, rumors surfaced alleging that Haerin was acting like a diva behind the scenes and treating staff poorly. However, numerous colleagues and staff members came to her defense, emphasizing her kindness and respectful nature toward everyone she works with. They noted that those who started the rumors weren’t even employed at the company during the period in question, effectively debunking the claims and reinforcing Haerin’s reputation as a warm and considerate person.
