Full Bio / Wiki
Junseo (Han Jun-seo, 한준서, b. 20 October 2006) is the leader and main vocalist of POLARIS, the four-member South Korean group based in Seoul. He’s the eldest of the four, raised in Seoul in a household that paired duty with warmth — a grandfather who had served, a home built on care, food and looking after the people around you. The group’s canon frames him as steady, warm and resolute, with a distinct function inside the group rather than a generic idol archetype.

He sang at family gatherings and in school choir before formal vocal training shaped a naturally warm tenor. Leadership followed as the social extension of the same instinct — keep the group centred, make sure everyone gets through the work together. Inside POLARIS he holds a precise register: a warm, steady tenor that acts as the group’s emotional anchor, rich and unforced, and owns the debut’s closing promise.

On the debut single 별빛 No Man’s Star (노맨스 랜드) — 120 BPM, A♭ major, a Korean-led bilingual lyric with English peak lines — his anchor is the final promise line “I’ll find you again.” His job across the track’s radio-static intro, falling pre-chorus, wide chorus and piano bridge is to hold the group’s centre rather than to own every section.

His public presence is grounded and calm — steady eye contact, a still point the other three can orient around rather than a spotlight-chasing frontman. He keeps an old photograph connected to his grandfather’s service, which is part of why the debut’s separation concept lands personally for him, and learned to cook during long practice nights so the members eat properly. Personality in three words: steady, warm, resolute. His current member marker inside POLARIS’s four-colour system is signal amber and warm gold.

What they are

Junseo is an AI-realised act from FARA Records — Fully Artificial, Radically Authentic, the AI-native label of SPATIALx. The lyrics, emotional brief, arrangement and production behind every act on the label come from human writers and directors. Suno renders the vocal and musical takes from there, and the results are handed back to be curated, re-prompted, edited and mastered until they say exactly what they were built to say. We don’t hide any of it — the seams are part of the art. This isn’t AI filler standing in for a band. It’s real songwriting, real direction, and a voice that didn’t exist before.
