From pageants to quant finance: the diverse careers of the ‘Single’s Inferno’ season 5 cast

Choi Mina Sue is an international pageant winner and communications student. She became the first Korean to win Miss Earth in 2022, one of the major global beauty pageants. Raised in Australia and educated in the United States at the University of Illinois Urbana-Champaign, she represents a transnational profile that blends media training with pageant experience.

Kim Go-eun won the 66th Miss Korea pageant in 2022 and works as a model. Pageantry in South Korea operates as both a cultural institution and a professional springboard into media and fashion. Her career sits at the intersection of public representation and commercial modelling, with experience in brand campaigns and appearances. 

Lee Joo-young trained in furniture design and now works as a craft and resin artist. Her practice focuses on handmade home décor pieces, a field that has grown alongside South Korea’s independent design market. Unlike contestants drawn from sport or entertainment, her career is rooted in studio work and material craft. That creative discipline broadens the occupational mix seen on Single’s Inferno this season.

Ham Ye-jin works as a freelance announcer and event host. Announcing in South Korea often requires formal training in broadcast presentation, diction and live hosting. Her professional life centres on communication in public settings, from corporate events to media engagements. In a cast that includes athletes and engineers, her media experience reflects another facet of contemporary professional culture.

Park Hee-sun studies Information Systems at Carnegie Mellon University, with academic interests that span technology and design. Carnegie Mellon is known for its strong computer science and engineering programmes, and her field sits at the intersection of data, systems architecture and user experience. She was also first runner-up at the Miss Korea 2024 pageant. Her presence highlights the growing visibility of tech-focused education among younger contestants joining Single’s Inferno.

Lee Sung-hun, also known as Samuel Lee, graduated from the University of California, Berkeley with a degree in computer science and applied mathematics. He previously worked as an AI engineer at Google and now works in quantitative trading in New York. Quant finance relies on mathematical modelling and algorithmic systems to analyse markets, placing him in one of the most technically demanding professions represented on Single’s Inferno to date.

Youn Hyun-jae has a background in IT and user interface design and was a runner-up in Mister International Korea 2024. His profile combines technical work with modelling and pageant experience. That dual track reflects a broader trend in which digital sector professionals also cultivate public-facing careers, particularly in modelling and brand work.

Kim Jae-jin trained in modern dance and works as a performer and instructor. Professional dance in South Korea spans commercial choreography, contemporary performance and education. His career is grounded in physical discipline and stage craft, bringing a performing arts perspective into the social dynamics of Single’s Inferno.

Song Seungil works in fashion marketing while also modelling. Fashion marketing involves brand positioning, campaign strategy and consumer engagement within a highly competitive retail sector. His career situates him within South Korea’s fashion industry, which continues to expand its global footprint.

Woo Sung-min works as an optician, reportedly connected to a family optical business. Optometry and eyewear retail form part of South Korea’s established small business landscape. His inclusion underscores that the cast is not exclusively drawn from media or sport, but also from traditional professional pathways.

Jo I-geon is active as an actor in Korean dramas and entertainment. Acting careers often require years of auditions, training and minor roles before wider recognition. His prior television exposure places him among the more media-experienced members of the Single’s Inferno cast.

Shin Hyeon-woo is a former athlete who now works as a handball coach. Coaching roles involve athlete development, tactical planning and programme management. His career reflects a continued engagement with competitive sport beyond active play.

Lim Su-been spent more than a decade as a baseball pitcher before transitioning into modelling after an injury. Professional baseball in South Korea is a structured and competitive field, and his athletic background informs his current work in fashion imagery and brand campaigns.

Single’s Inferno presents a cast whose off-screen careers span national sport, global pageantry, quantitative finance, design and small business. The series remains a dating show, but its participants arrive with established professional identities that extend well beyond the island setting.
