Who Is Jiwoo? Meet the Leader of Hearts2Hearts

Jiwoo is a South Korean singer, dancer, and leader of the SM Entertainment girl group Hearts2Hearts (하츠투하츠), affectionately known as H2H. Born Choi Ji-woo on September 7, 2006, in Godeok-dong, Gangdong-gu, Seoul, Jiwoo debuted with Hearts2Hearts on February 24, 2025, guiding seven groupmates — Carmen, Yuha, Stella, Juun, A-na, Ian, and Ye-on — through the group’s whirlwind first year.

For K-pop fans who love a leader with both grace and grit, Jiwoo delivers on every front: years of ballet training, a calm and dependable personality, and a growing list of rookie trophies that prove Hearts2Hearts’ star is only rising.

Early Life and Trainee Journey

Jiwoo grew up in Seoul and trained in ballet for six to seven years before her idol career even began. SM Entertainment discovered her in the sixth grade during an unexpected encounter — she was simply shopping at a convenience store when a scout approached her. That chance meeting kicked off a six-year trainee journey, one of the longer training periods among Hearts2Hearts’ eight members, giving Jiwoo time to refine her dancing, rapping, and vocal skills before debut.

Debut and Leadership Role

Hearts2Hearts officially debuted on February 24, 2025, with the single album The Chase. As leader, Jiwoo represents the group during official greetings, interviews, and behind-the-scenes decision-making. She’s also credited as a dancer, rapper, and vocalist, making her one of the most well-rounded members in the lineup. The group’s debut broke first-week sales records among girl group debuts and earned Hearts2Hearts a music show win on The Show just 15 days after their first stage — a milestone Jiwoo has cited as a proud early memory.

Since then, Hearts2Hearts has released the singles Style and Rude!, along with the EPs Focus and Lemon Tang, and collected nine rookie awards throughout 2025 — the most of any group that debuted that year.

Personality and Hobbies

Despite her shy, reserved nature offstage, Jiwoo is known for being straightforward, organized, and dependable as a leader — qualities that groupmates and fans in the S2U fandom frequently highlight. She loves gelato (especially strawberry flavor), can juggle thanks to a school PE class, and often serves as the group’s unofficial photographer, snapping candid pictures of her groupmates. She also keeps a personal diary that she brings on every trip.

Jiwoo wears glasses and has a pet dog named Kong back home, along with an older brother born in 2004. Her stated role model is aespa’s Karina, another SM Entertainment leader known for her dance skills.

Jiwoo’s Role in Hearts2Hearts

As leader, Jiwoo balances performance duties with representing the group publicly, all while contributing dance, rap, and vocal parts across Hearts2Hearts’ discography. Her ballet background has translated into standout, graceful choreography moments, including a widely praised solo ballet segment performed during one of the group’s award-show stages. As Hearts2Hearts continues to grow its global fandom S2U, Jiwoo’s leadership remains central to the group’s steady rise in the competitive 5th-generation K-pop landscape.
