Jeong Hyerin

When tripleS first launched, HyeRin was the group's very first maknae (youngest member). However, she rarely acted like a typical coddled youngest child.

Having started her trainee life away from home at just 13 years old, she developed high levels of self-reliance early on.

HyeRin balances a very cool, composed exterior with a deeply expressive and funny interior.

Fans respect her for being incredibly level-headed, consistent, and mentally resilient. She is determined to hit her personal goals without comparing herself competitively to others.

One of the internet's absolute favorite running gags is watching HyeRin get visibly frazzled or bewildered. She is naturally calm and collected, so watching her face twist into utter confusion when her 23 groupmates start acting completely wild and chaotic is a massive source of fan memes.

She is incredibly witty and knows exactly how to entertain. Fans note that she loves dropping into different "characters" and playfully messing with or teasing her members just to make them laugh. She's also widely known as the ultimate foodie of the group (with a legendary love for tteokbokki and malatang) and has a quirky, internet-famous talent for catching flying food perfectly in her mouth.

While K-pop personality profiles can shift over time, fan analysis and online databases consistently group her under the ESTP or ESTJ umbrellas. The Internet Consensus: Fans widely identify her as a textbook "T" (Thinking) type. Her rational, straightforward, and highly practical approach to solving problems—and her disciplined leadership when directing complex dance routines—screams structured efficiency.

Visually and socially, she can look very chic, sharp, and sometimes a bit intimidating when she’s quiet or focused on dancing. But the moment she smiles or does something clumsy, that cold exterior completely melts away.

Formed by Modhaus, tripleS is a revolutionary 24-member multi-national K-pop girl group celebrated for its decentralized, fan-directed concept where listeners use the Cosmo app to vote via "Gravity" on rotating sub-units, concepts, and tracklists. The historic, record-breaking lineup is tracked by their chronological reveal order from S1 to S24, consisting of Yoon Seoyeon, Jeong Hyerin, Lee Jiwoo, Kim Chaeyeon, Kim Yooyeon, Kim Soomin, Kim Nakyoung, Gong Yubin, Kaede, Seo Dahyun, Kotone, Kwak Yeonji, Nien, Park Sohyun, Xinyu, Mayu, Lynn, Joobin, Jeong Hayeon, Park Shion, Kim Chaewon, Sullin, SeoAh, and Jiyeon. Balancing a massive variety of international talents, main vocal powerhouses, and elite dance aces, the group initially promoted in smaller sub-units before officially combining their immense collective energy to unite and dominate the stage as a complete 24-member powerhouse.cal
