Sung Han Bin

• Sung Hanbin was born on June 13, 2001, in Cheonan, South Korea. He grew up in South Chungcheong Province before pursuing his education and entertainment career in the Seoul metropolitan area.

• His birth name and stage name are both Sung Hanbin (성한빈). He is frequently referred to simply as Hanbin, while international publications sometimes separate his given name as Han Bin.

• Hanbin is the leader of ZEROBASEONE. He was selected to lead the group after its formation through Boys Planet and continued in that role following its transition to a five-member lineup in 2026.

• He is not ZEROBASEONE's oldest member. Kim Jiwoong, born in December 1998, is older than Hanbin, making the group's leadership structure different from the age-based hierarchy some fans expect.

• Hanbin has a younger sister who is an athlete. She has been involved in competitive sport climbing and has represented South Korea at the national level.

• His mother owns a café in Pyeongtaek. Before becoming an idol, Hanbin helped at the family business and gained experience preparing drinks and serving customers.

• He studied K-pop performance at Dong-ah Institute of Media and Arts. His education gave him additional opportunities to develop his skills in dance, music and professional performance.

• Hanbin was an experienced street dancer before becoming a K-pop idol. Unlike trainees who begin learning dance only after joining an entertainment company, he had already developed technical expertise through independent training and competitions.

• Waacking is one of his signature dance specialties. The style features fast, rhythmic arm movements, expressive poses and musical interpretation, allowing Hanbin to demonstrate both precision and personality.

• He is also skilled at tutting. Tutting uses angular movements of the hands, fingers and arms to create geometric shapes, making it particularly well suited to dancers with exceptional control and coordination.

• Hanbin participated in street-dance competitions before debuting. His competitive dance background helped establish his reputation as a technically skilled performer rather than someone who learned only idol choreography.

• He worked as a backup dancer before becoming famous. His pre-debut dance work included performances connected to established K-pop artists, giving him professional stage experience before Boys Planet.

• He previously trained under Cube Entertainment. His time at Cube came before he competed on Boys Planet representing Studio GL1DE.

• Hanbin became close friends with Seok Matthew while they were trainees. The two trained together at Cube Entertainment and reportedly shared a dorm, developing a friendship that continued into their time on Boys Planet.

• Hanbin and Matthew eventually debuted in the same group. Their friendship became a particularly popular storyline among Boys Planet viewers because both contestants earned places in ZEROBASEONE.

• He performed "Say My Name" during the artist battle mission. The bright, youthful song highlighted a softer performance style compared with the more intense concepts he had previously performed.

• Hanbin was the main vocalist of the "Hot Summer" team during the finale. His role demonstrated the vocal responsibilities he could handle in addition to his established dancing abilities.

• He maintained first place for most of Boys Planet. Hanbin led the rankings throughout the competition until the final episode, when Zhang Hao finished first and Hanbin placed second.
