Ye-on

Ye-on (예온), born Kim Na-yeon (김나연), arrived in Hearts2Hearts as the group's youngest member but never as a lightweight presence. Under SM Entertainment, she quickly stood out for a warm tone, quick reactions in fan content, and the kind of bright facial expression that keeps the camera on her even in crowded group formations.

Her path into SM was unusually fast. Ye-on was scouted through Instagram DM while still in elementary school, trained for roughly two years, and passed both middle school and high school equivalency exams before debut. That compressed timeline matters because it explains why fans talk about her upside so often. She entered the market young, but not raw.

Since Hearts2Hearts debuted in February 2025 with The Chase, Ye-on has helped anchor a run that also includes Style, Focus, and Rude!. She has cited Taeyeon as a role model, and you can hear why people make that connection: the appeal is not volume for its own sake, but clarity, tone, and emotional read. As the group scales, Ye-on already feels like one of its long-game assets.
