Seoung Yong Sook BIOGRAPHY
Seoung Yong Sook (Korean: 서웅 용숙; born April 18, 1997) is a South Korean fiction professional dancer and choreographer based in Tokyo, Japan. Known for his sharp, disciplined stage presence and his signature “Scorpion” persona, he works as a freelance performer, movement coach, and choreography director for music videos, idol training programs, and commercial productions.
Early Life
Seoung Yong Sook was born in Seoul, South Korea, to architect Seoung Dong-Min and former opera singer Hyo Eun Jung. He spent part of his childhood living with his grandparents in a rural area, where he was introduced to street dance after watching a group of local teenagers practice outdoors. Inspired, he began training on his own, experimenting with rhythm and movement.
As a teenager, Seoung became known for his rebellious and unpredictable behavior, shaped by family tensions and a distant relationship with his older brother. At age 15, he auditioned for the national talent program Asia Talent, where he placed in the top 10 and entered a multi-year trainee system.
Career
2012–2015: Trainee Period
During his trainee years, Seoung underwent intensive training in dance, stage performance, and physical conditioning. He developed a unique style blending urban dance with capoeira elements, beginning formal capoeira practice at age 16. His intense, controlled personality earned him the nickname “Scorpion”, which later inspired the scorpion tattoo on his right arm.
2015–2019: Q360 and Early Work
Seoung debuted in 2015 with the dance performance group Q360, appearing on national television programs, events, and commercial projects. The group remained active until 2018–2019, gradually disbanding as members pursued individual paths.
In late 2019, Seoung terminated his contract with the Korean agency KM&D Corp. to focus on solo projects and choreography work.
2020–present: Move to Japan and Freelance Career
In early 2020, Seoung relocated to Tokyo with his manager, Hwang Sun Hi (“Sunny”), seeking broader opportunities. Without attending formal language programs, he learned Japanese through daily life and on-set work. Over time he became a sought-after freelance choreographer for dance crews, TV networks, and idol agencies, including POPcorp, NTV sub-studios, and various independent production companies.
His work spans:
• background dancer casting
• music video choreography
• stage performance direction
• movement and conditioning training for idols
• custom workout programs for performers
He is known for strict discipline, high standards, and a minimalist, high-intensity teaching style.
Artistry and Style
Seoung’s choreography emphasizes:
• sharp, controlled movements
• capoeira-inspired sweeps and rotations
• urban/hip-hop footwork
• strong rhythmic precision
His persona combines quiet intensity, emotional distance, and methodical determination. Although often perceived as cold or intimidating, he is respected for his professionalism and consistency.
Personal Life
Seoung is described as private, solitary, and highly disciplined. He dislikes clutter, loud environments, and crowded spaces, and is sensitive to strong scents. He enjoys running at dawn, capoeira, boxing, and highly spiced food. He avoids nightlife and dedicates most of his time to training and work.
Although he maintains little contact with his family, he privately records monthly video journals reflecting on his career and life in Japan. He has expressed a long-term wish to reconnect with his mother, though he speaks about his family rarely.
