GEMINI Member Profiles:

Minguk 

Stage Name: Minguk (민국)

 Birth Name: Jeong Minguk (정민국) 

Position: Main Vocalist & Rhythm Guitarist

Birthday: May 27, 1997

Zodiac Sign: Gemini

Height: 180 cm

Blood Type: AB 

 MBTI: ENFP-T

Nationality: Korean -American

 Vocal Tone & Style: Baritone rasp with warmth, pain, and control, heavy, introspective, emotionally charged 

Representative Color:  Burnt Crimson (#9C1F1F) 

Minguk has a naturally charismatic presence, often exuding charm with a touch of cheekiness. He tends to be playful in interviews and on social media, showing a sense of humor and a laid-back vibe that makes him approachable to fans. He is known for being genuinely open about his thoughts, emotions, and experiences. Whether he’s talking about mental health, his creative process, or personal challenges, he tends to be straightforward and vulnerable, which fans deeply appreciate.

Minguk is very emotionally in tune, and this comes through in his music. His raspy, soulful voice complements his introspective songwriting style, often touching on themes of identity, love, loneliness, and inner conflict. His artistry reflects a thoughtful and sensitive nature. He isn’t afraid to go against the grain or push boundaries, which sets him apart in the K-pop and alt-rock scenes.

As the leader of Gemini, Minguk exhibits a calm and mature leadership style. He leads more by inspiration and encouragement than strict direction. His bandmates have often mentioned how he helps hold the group together with emotional support and creative guidance.

While he’s warm with fans and affectionate toward his bandmates, there’s also a reserved, introspective quality to him. He doesn’t always seek the spotlight in a loud or overly extroverted way. Instead, he seems to observe and reflect, lending a poetic air to his persona.

The only member in the band he regularly butts heads with is his twin brother, Daehan. Though they share a deep, unshakeable bond, their differences often lead to creative clashes—Minguk’s introspective approach sometimes conflicting with Daehan’s more impulsive energy. Still, their dynamic adds a unique tension and chemistry to the group that fans love.

Minguk is the older of two siblings, born just six minutes before Daehan. The two are mirror twins—Minguk is left-handed, while Daehan is right-handed—a reflection of their contrasting personalities. Their bond is complex, shaped as much by competition as by love and loyalty.

At thirteen, Minguk's family relocated to Los Angeles, where he discovered his passion for music in the diverse and vibrant indie scene. It was during this time that he began writing songs, experimenting with sound, and finding his voice. At eighteen, he returned to Seoul to pursue music professionally—bringing with him a unique blend of Western influence and Korean sensibility that now defines much of Gemini’s sound.

 Daehan 

Stage Name: Daehan (대한)

Birth Name: Jeong Daehan (정대한)

Position: Drummer, Sub Vocalist / Atmospheric Vocal FX (Echoes, ghost harmonies)

 Birthday: May 27, 1997

Zodiac Sign: Gemini

Height: 181 cm

Blood Type: AB 

MBTI: ESFJ-T

Nationality: Korean -American

Vocal Tone & Role: Doesn’t sing often, but when he does, it’s haunting and cold, 

Specializes in background echoes, vocal distortions, or spoken lines during live performances 

Think: the voice behind the storm “If Minguk remembers, Daehan suppresses.”

 Representative Color: Steel Blue (#2F4F6A)

Daehan is a natural extrovert—confident, social, and unapologetically himself. Whether he’s on stage, hosting a podcast, or just interacting with fans online, he brings a high-energy, personable presence that makes him incredibly likable. His loud laugh, expressive reactions, and easygoing nature often make him the center of attention in the best way.

Despite his fun-loving exterior, Daehan is also incredibly loyal and protective, especially toward his bandmates. He often takes on a big brother role, making sure everyone feels supported and safe—both on stage and behind the scenes. This mix of playfulness and fierce protectiveness is a huge part of his charm.

One of Daehan’s trademarks is his unfiltered honesty. He’s not afraid to speak his mind, and he often uses humor and self-awareness to dive into serious conversations—from industry pressures to body image to mental health. His ability to keep things real without being cynical makes him feel grounded, relatable, and refreshingly human.

He’s become a kind of modern role model—showing that men can be both strong and soft. Daehan is outspoken when it comes to topics like toxic masculinity, mental health advocacy, body positivity, and supporting women in the music industry. His empathy and openness have earned him a great deal of respect—not just from fans, but also from peers within the industry.

Daehan is the kind of person who can light up a room with laughter, defend his people with unwavering loyalty, and drop a verse that hits just as hard as his gym routine. His energy is magnetic, his confidence contagious, and his heart, always in the right place.

Though he's the younger twin by six minutes, Daehan often feels like the one "in control" on the surface—more outspoken, more impulsive, more visibly confident. This dynamic is part of why he and Minguk often butt heads, their personalities clashing in ways only siblings can. But beneath the bickering lies an unshakable bond. Daehan and Minguk are each other's ride-or-dies—fierce rivals and fiercest allies, bound by blood, music, and history.

At thirteen, Daehan's family relocated to Los Angeles, where he found himself immersed in the city's diverse and vibrant indie scene. It was during this period that he fell in love with rhythm and began teaching himself how to play the drums. Music quickly became an outlet for his energy and emotions. At eighteen, he moved back to Seoul with Minguk to pursue music professionally—bringing with him a bold, hybrid style shaped by West Coast swagger and deep-rooted emotional grit.

Hoseok

 Stage Name: Hoseok (호석)

Birth Name: Lee Hoseok (이호석)

Position: Lead Guitarist, Screamer / Harsh Vocalist

Birthday: August 8, 1998

Zodiac Sign: Leo

Height: 178 cm

Blood Type: B

MBTI: ESTP-A

Nationality: Korean

 Vocal Tone & Role: Specializes in harsh vocals, growls, and gritty bridges

Doesn’t sing often, but when he does, it’s intense and unpolished — by design

Screams like he’s trying to break the sky

Guitar Style: Raw, fast, and untamed — heavy on distortion, slides, wild whammy action

Known for breaking picks on stage

Uses an all-black guitar with fanglike edges and crimson LED inlays

Representative Color: Obsidian Red (#670000)

Hoseok is the sonic berserker of GEMINI — his guitar work is raw, aggressive, and deeply physical. He plays like he's fighting the instrument into submission: heavy distortion, frantic slides, and violent whammy dives. Picks don’t last long in his hands. Neither do expectations.

Vocally, he specializes in harsh screams, layered growls, and guttural textures. When he delivers a line, it’s not just heard — it’s felt, like a wound tearing open mid-track. His screams aren’t clean or pretty — they’re visceral, by design.

Possessed. Hoseok doesn’t just perform — he erupts. Every movement is charged. He stalks the stage like it owes him something. The mic stand isn’t a prop — it’s a weapon. He plays guitar like he’s brawling with it and screaming like the sky’s supposed to scream back.

There’s no acting in his stage presence. It’s just Hoseok, unleashed.

Blunt, reckless, and addictively fun, Hoseok is the kind of guy who’ll challenge you to a push-up contest in the middle of a press shoot. He has a sharp tongue, louder laugh, and zero filter, with a glint in his eye that says he’s either about to do something brilliant—or stupid. Possibly both.

He plays the “alpha” role with swagger, but in truth? He’s loyal, emotional, and a total softie under the fire. He’ll go feral over injustice, cry over a dog video, and threaten violence if someone messes with a member. Hoseok dares chaos, but lives for connection.

Hoseok is the unleashed beast of GEMINI — all instinct, aggression, and chaotic magnetism. As the “Fang” of the twin duo, he brings raw edge and emotional wildfire to the band’s identity. Whether he’s shattering speakers with a scream or dragging the members into his next reckless idea, Hoseok lives unapologetically — a storm of sound, fury, and surprising tenderness.

Their household was traditional and emotionally distant — not cruel, but cold. Expectations were high, but praise was sparse. As kids, they relied on each other more than anyone else, forming a bond that was both codependent and competitive.

Hoseok fought for attention — loud, brash, and quick to act. Hojun learned to navigate silently — watching, calculating, mastering the rules so he could later bend them.

Their introduction to music came through rebellion.

At age 12, they discovered their uncle’s old CD collection hidden in a storage closet: Led Zeppelin, Deftones, Nirvana, and experimental Korean rock bands from the ‘90s. Hojun was drawn to the bass — the low, grounding energy. Hoseok to the distortion and fury.

They began learning their instruments in secret, teaching themselves with secondhand gear and late-night YouTube tutorials in their shared room. By 15, they were sneaking out to underground clubs in Hongdae to study live bands. By 17, they were writing music of their own — raw, angry, and full of things they weren’t allowed to say out loud.

What began as survival became obsession. Music was where Hojun found control, and Hoseok found freedom. They forged a pact: make it or break trying. At 18, they joined the KR▲KEN trainee program — and haven’t looked back since.

Hojun

Stage Name: Hojun (호준)

Birth Name: Lee Hojun (이호준)

Position: Bassist, Clean Sub Vocalist

Birthday: August 8, 1998

Zodiac Sign: Leo

Height: 178 cm

Blood Type: B

MBTI: INTJ-A

 Nationality: Korean

Vocal Tone & Role: Provides subdued clean vocals, ghost harmonies, or spoken word bridges

His voice is smooth, low-toned, and controlled — like a voice from another realm

Contrasts Minguk’s emotional rasp and Hoseok’s rawness with surgical calm

Fans say he “sings like he’s telling fate a secret”

Bass Style: Elegant and tight — builds tension through restraint

Uses deep-toned, fretless bass for liquid, celestial sound

Rarely shows off, but when he solos, it stuns

Representative Color: Celestial Silver (#C0C0C0)

Hojun doesn’t need to move to be felt. He’s the eye of the storm — commanding with silence, radiating calm with razor-sharp precision. His stage presence is ghostlike and divine: not aggressive, but inescapably powerful. 

Hojun is the still water with infinite depth. He doesn’t speak often, but when he does, his words cut through chaos like a blade. He’s practical, deeply observant, and usually two steps ahead of the room. While others get loud or heated, Hojun stays cold — not out of detachment, but because he’s always analyzing.

He’s the one who grounds the team, de-escalates arguments, and makes executive decisions when needed. If Hoseok is the fist that hits first, Hojun is the hand that guides the blade.

And though he often appears detached, his loyalty is absolute — he protects his bandmates like holy relics.

Born just minutes apart, Hoseok and Hojun are identical twins . Despite their personalities being polar opposites, Hoseok and Hojun are the definition of opposites attract.  They are two brother tide at the hip, and despite their differences get along very well.  It's rare to see one without the other.

Their household was traditional and emotionally distant — not cruel, but cold. Expectations were high, but praise was sparse. As kids, they relied on each other more than anyone else, forming a bond that was codependent, leaning into each other.

Eunho (은호)

 Stage Name: Eunho (은호)

Birth Name: Yoon Eunho (윤은호)

Position: Main Lyricist, Synthesizer, Producer, Sub Vocalist

Birthday: October 21, 1999

Zodiac Sign: Libra

Height: 176 cm

Blood Type: AB

MBTI: INFJ-T

 Nationality: Korean

Vocal Tone & Role: Soft but intentional — almost spoken, like a confessional

Often sings in the background with subtle harmonies or fragmented lines

Known for breaking the fourth wall with his delivery — makes you feel like he's reading your mind

Representative Color: Moonlit Grey (#A8A9AD)

Eunho is known for being intensely driven, focused, and private. As the brain behind much of GEMINI’s music, he’s deeply immersed in the creative process — not just as a performer, but as the producer, arranger, and sometimes perfectionist behind the scenes. He’s meticulous with sound, lyrics, and performance, often spending long hours in the studio honing every detail.

Despite his quiet, sometimes aloof appearance, Eunho is deeply thoughtful and intentional. He may not be the most outwardly affectionate member, but his loyalty and care show through his actions — writing songs that speak to each member’s strengths, and leading the vocal unit with quiet strength. He’s respected for his discipline, intelligence, and leadership. He doesn’t speak often during chaotic group moments, but when he does, it's usually with dry humor or sharp insight. He’s playful in his own way — especially when he’s relaxed with the members — and has a tsundere charm: acts cold, but cares deeply. 

Enho is a creative powerhouse wrapped in quiet discipline. He balances logic and artistry, seriousness and sarcasm, hard edges and hidden warmth. While he may seem distant at first, those who take the time to observe realize he’s one of the most emotionally intelligent and dependable members of Gemini. Extremely introverted — tends to wander off in green rooms just to write or record voice memos. Even with his sister he is often quite. He has hours-long conversations with Eunhee without saying a word.

Eunho is just minutes older than his twin, and it follows them in adult life as well.  Eunhee always follows silently after her older brother.

Eunhee

Stage Name: Eunhee (은희)

Birth Name: Yoon Eunhee (윤은희)

Position: Keyboardist, Soundscaper / Producer (Live FX, Synth Design)

Birthday: October 21, 1999

Zodiac Sign: Libra

Height: 167 cm

Blood Type: AB

MBTI: INTP-T

Nationality: Korean

Keyboard Style & Role: Plays multiple synth layers simultaneously — analog, digital, modular

Creates GEMINI’s atmospheric textures, melodic FX, ambient intros/outros

Never sings or speaks on stage — her presence is through sound alone

Known for completely altering setlists live using on-the-fly filter edits

Representative Color:  Iridescent Violet (#6F42C1)

Much like her brother, Eunhee is extremely introverted.  She very rarely speaks, but when she does the whole group listens.  She's not only Eunho's little sister, but the baby sister of the entire group, and the only one that evades the older one's pranks. On stage she's often positioned alone in darkness or bathed in LED static (her preference.) Off-stage, she makes the others chuckle with her hilarious deadpan stare, and is obsessed with sound design. You'll often find her talking to machines more than she does people.

Eunhee hates interviews, and often leaves talking to the older member of the group.  Her fans often track her in the rare occasions that her voice is picked up on other members' lives. Once on a video tour Eunho gave of their dorms he showed Eunhee's room while she was out.  Fans were charmed to see a purple cosmos in her room, and it bathed in neon purple light. On rare occasions, Eunhee will go live, positioning the camera on her keyboard, and quietly play songs for her fans. 

Eunhee is the group’s most elusive member — not because she’s distant, but because she exists on a different wavelength. She's not shy. She's selective. She's not quiet. She's resonant. Where others shine brightly, Eunhee hums like interference — a necessary anomaly that gives the group's identity depth and mystery.

Eunhee is just minutes younger than her older brother, Eunho, and it has followed them into adulthood.   Eunhee always follows silently after her older brother.
