She became the first member of TWICE to receive an official writing credit when she wrote the rap verse for the group’s cover of J.Y. Park’s “Precious Love” on their 2016 album “Page Two.” This milestone marked the beginning of an impressive and growing list of contributions.

LIL FANTASY vol.1 achieved strong physical sales, moving over 174,816 copies, and accumulated more than 10.5 million YouTube views across its content. The album earned Chaeyoung a nomination at the 2026 Korean Music Awards in the Best K-Pop Album category, further cementing her credibility as a serious solo artist.
Awards and Recognition
Chaeyoung’s talent has not gone unnoticed by the industry. In 2025, she won the UPICK Global Choice Female award at the D Awards, a recognition voted on by fans worldwide. Her nomination at the 2026 Korean Music Awards for Best K-Pop Album with LIL FANTASY vol.1 added another layer of professional validation to her growing solo career.

Personal Life and Relationships
Relationship with Zion.T

The following day, JYP Entertainment confirmed the reports, making it an officially acknowledged relationship. Zion.T is approximately 10 years older than Chaeyoung, and the couple reportedly had already been dating for around six months before the news became public.
Health and Hiatus
In November 2025, JYP Entertainment announced that Chaeyoung would be taking a temporary hiatus from certain activities following her diagnosis with vasovagal syncope, a condition that causes sudden drops in heart rate and blood pressure. The announcement came as a concern to fans, but Chaeyoung showed her resilience by returning on January 7, 2026, joining her TWICE members as they traveled to Vancouver for the North American leg of the THIS IS FOR WORLD TOUR.
Personality, Interests, and Fun Facts
Away from the stage and studio, Chaeyoung is known for being a quiet and introspective individual with a rich inner world. She is a passionate visual artist who loves to draw, and her illustrations have appeared on official merchandise and music releases. She plays the guitar and has a love for music that spans genres well beyond K-pop.
Chaeyoung is a self-described Pokémon fan, with Togepi, Pikachu, and Eevee being her favorites. She adores the classic TV show Sesame Street and reportedly has a room filled with characters from the series.

Her favorite colors are black and purple, and her favorite foods include baked salmon and Anago sushi. She is close friends with BLACKPINK’s Rosé and has maintained friendships with fellow artists from her trainee days, including Somi. Chaeyoung also has two beloved pets named Logan and Nereri.

Collaborations and Appearances Beyond TWICE
Chaeyoung’s artistic footprint extends well beyond her group activities. She collaborated with K/DA on the track “I’LL SHOW YOU” alongside Nayeon, Sana, Jihyo, Bekuh Boom, and Annika Wells. She also lent her creative touch to Coco & Clair Clair’s “Pop Star (Chaeyoung Remix)” in 2023 and collaborated with sokodomo on “WAKE UP” in 2025.
Her melody project releases, including “Alone” (2016), “Switch To Me” with Dahyun (2021), “Off My Face” (2022), and “Weatherman” (2023), show a consistent drive to express herself through music even outside of major releases.

Why Chaeyoung Stands Out in K-pop
Son Chae-young is not a performer who fits neatly into a single category. She is a rapper who writes her own lyrics, a singer who supports her group vocally, a visual artist who designs products, a guitarist who composes her own music, and a solo artist who delivers deeply personal work. Her English name Katarina Son adds another layer to her internationally recognized identity, while her Korean name 손채영 connects her deeply to her roots.
With chaeyoung full name now firmly established in K-pop history, fans and industry observers alike continue to watch her evolution with great anticipation. Whether performing with TWICE on a world tour stage or releasing deeply personal solo work, Son Chae-young continues to prove that she is one of the most compelling and complete artists of her generation.
