In the vibrant world of K-pop, a leader often sets the tone. For the boy band Tomorrow X Together, that steady presence is Soobin. He guides the five-member group known as TXT with a quiet confidence.
His journey to music began at age fifteen. He sent an email audition to Big Hit Entertainment in late 2015. After passing the audition, he committed to three years of intense training.
This preparation led to the group’s formation in 2019. Standing at 187 centimeters, he became the tallest member. His physical stature matches his observant and thoughtful nature.
Born in Ansan, South Korea, he is the youngest of three siblings. His path from a trainee to a leader traces a compelling story. It is a story of talent meeting precise timing within a competitive industry.
Early Life and Training: From Ansan Roots to Big Hit Beginnings
Before the spotlight found him, a teenager in Sangnok District was navigating the ordinary challenges of school and family life. His journey began far from the stage lights, rooted in the everyday rhythms of Ansan.
Childhood, Family, and Educational Foundations
Growing up as the youngest of three children shaped his early perspective. His older brother provided guidance six years ahead, while his sister offered wisdom from a full decade of experience. This family dynamic fostered both independence and observation.
He attended Kyongsu Middle School before briefly enrolling at Ansan High School. The demands of trainee life soon forced a difficult choice between conventional education and musical ambition.
The Big Hit Trainee Journey and Early Challenges
At fifteen, he sent an email audition to Big Hit Entertainment in December 2015. The digital submission led to acceptance three months later, beginning a three-year training period.
Those years tested more than just dance and vocal skills. He struggled with shyness and loneliness, finding it difficult to connect with fellow trainees for a long time. The experience built resilience that would later serve him well.
Today, those early challenges inform his approach to leadership. The time spent navigating trainee life created empathy for newer members joining the company.

This empathy helped him bond early with fellow member Kai. Their connection is a key part of the group’s synergy.
He spends a lot of time with all the members, even during their free time. This constant togetherness has built a deep comfort level.
