Meet Ye-on: The Youngest Voice Of Hearts2Hearts

Every K-pop lineup needs its maknae, and in Hearts2Hearts that role belongs to Ye-on, the group’s youngest member and one of its steadiest vocalists. Debuting on February 24, 2025, under SM Entertainment, Ye-on quickly stood out for a voice far more controlled than her age would suggest.

Born Kim Na-yeon on April 19, 2010, in Yangsan, Gyeongsangnam-do, Ye-on started singing at just five or six years old. She joined SM Entertainment through DM casting while still in the sixth grade, and after roughly two years of training, she debuted as part of Hearts2Hearts’s original eight-member lineup, making her one of the youngest active idols at any major Korean agency.

Training, Debut, And Life As Maknae

Despite her short trainee period, Ye-on’s vocal foundation — built from years of singing and a background in musicals — helped her secure a spot as one of Hearts2Hearts’s core singers. Members and fans alike describe her as the group’s “Cutie,” known for her eye-smile and calm, sunny demeanor. She has stayed close to bandmate Ian, sharing a dorm room with her since debut.

Since “The Chase,” Ye-on has promoted through every subsequent Hearts2Hearts release, including “Style,” “Focus,” “Rude!,” and “Lemon Tang.” Alongside her group schedule, she completed both her middle school and high school equivalency exams in 2025, allowing her to keep up her education without pausing her idol career.

Ye-on’s Profile At A Glance

As Hearts2Hearts’s maknae, Ye-on continues to grow her presence on stage while staying true to the gentle, cheerful image that first won fans over. With a strong vocal base and years of promotions still ahead of her, she remains one of the group’s most promising long-term assets.
