🎤 Seunghyun (승현) – Leader, Rapper, Dancer
Seunghyun is the oldest member and leader of AIMERS. As the group’s main rapper and one of its lead dancers, he brings a cool, commanding energy to every performance that makes him impossible to look away from.
Seunghyun
- Stage Name: Seunghyun (승현)
- Birth Name: Lee Seung-hyun (이승현)

He was the very first AIMERS member to be officially revealed to the public.
He trained for a full four years before making his debut – real dedication to the craft.
Before AIMERS, he was a member of the boy group SPECTRUM, where he went by the stage name “Villain” (빌런) – a name he chose because he wanted something unique and meaningful.
His nicknames include Villain, Angel (천사), and Lee Seung – quite the range, right?
He is a certified Jjajang Ramen specialist – no, really, his listed “specialty” is making ramen, especially jjajang style.
His favorite colors are black and red, which also happen to perfectly match his on-stage vibe.
He was born at 6:40 AM, according to a member presentation video.
His personal motto is the refreshingly candid “Let’s be honest as we are.”
He stands at the tallest position in the group at 180 cm, tied with Yoel.
He announced his mandatory military enlistment as an active-duty soldier on April 27, 2026.
🎙️ Eunjun (은준) – Main Vocalist
Eunjun is the vocal powerhouse of AIMERS. As the main vocalist, he carries the group’s sound with a warmth and range that fans have absolutely fallen for. He’s also arguably the most “soft and sweet” member of the group – a total contrast to the intense stage presence he brings to performances.
Eunjun
- Stage Name: Eunjun (은준)
- Birth Name: Choi Eun-jun (최은준)
- Position: Main Vocalist
- Birthday: August 6th, 1999

- Weight: 64 kg (141 lbs)
- Blood Type: AB
- MBTI Type: ISFP
- Nationality: Korean
He was the second member announced as part of the AIMERS lineup.
Like Seunghyun, he is also a former member of SPECTRUM, making them the only two in AIMERS with that shared history.
Both Eunjun and Seunghyun were revealed together in July 2021 through a dance cover of “Jasmine” by DPR LIVE – an iconic first impression.
His nicknames are genuinely adorable: Mochi, Maknaengi (막냉이), Bbojjaki (뽀짝이), and Sticky Rice Cake.
His official listed “specialty”? Eating well. A man of culture.
He only trained for 2 years before debuting, making him one of the shorter training periods in the group.

His blood type is AB, which Koreans often associate with creativity and unpredictability.
Eunjun enlisted for mandatory military service on February 23, 2026, with an expected discharge date of August 22, 2027.
🎶 Doryun (도륜) – Vocalist
Doryun is the quiet force of AIMERS. He’s the kind of member who doesn’t need to be the loudest in the room to make an impact – his steady vocal tone and grounded presence give the group a solid emotional anchor.

He trained for just 1 year before debuting – the shortest training period of all six AIMERS members.
His MBTI type is ESTJ – meaning he’s organized, dependable, and great at getting things done.
He was born on May 1, 2000, making him a Taurus, a sign known for being reliable and hardworking.
His stage name Doryun (도륜) uses the syllables of his real name, Kim Dor-yun (김도륜).
Despite his “stone” nickname, fans note that he opens up a lot on variety shows once he gets comfortable.
He weighs the least among the taller members, at 60 kg for a height of 173 cm.
He is often considered one of the most underrated vocalists in the AIMING fandom – those who notice him, love him fiercely.
💃 Yoel (요엘) – Vocalist, Dancer
Yoel is the name that always makes people do a double-take – it’s unusual for a Korean idol, and that’s exactly the point. He’s one of the most visually dynamic members on stage, combining polished dance skills with a vocal tone that’s all his own.
Yoel
- Stage Name: Yoel (요엘)

- Nationality: Korean
He was the fourth member to be revealed.
His full name is Kim Yo-el (김요엘), but because “Yoel” doesn’t sound like a typical Korean name, people often assume he was born abroad. He wasn’t – he’s a Seoul boy through and through, born in Gangseo-gu, Seoul.
His nickname is Yokyangi, a cute nickname coined by fans and members.
He trained for four years before debuting – tied with Seunghyun for the longest training period.
His MBTI is ENTJ, making him one of the natural “commanders” of the group – confident, strategic, and driven.

He is known among fans for his razor-sharp dance lines and clean execution in group choreography.

He was born on January 25, 2001, making him one of the younger half of the group despite his strong presence.
🐕 Seunghwan (승환) – Vocalist, Dancer
Seunghwan is the member who got stuck with one of the best nicknames in all of K-pop: Samoyed. His fluffy, bright energy is genuinely infectious, and fans adore how he manages to be simultaneously goofy and polished.

He trained for 2 years before making his debut.
His MBTI is ESFP-T, which explains a lot – he’s enthusiastic, fun-loving, and thrives in social settings.
He is the youngest of the two “Seung” members, born on April 6, 2002.
He’s an Aries ♈ – a sign known for boldness and passion, which tracks perfectly.
Seunghwan and Wooyoung are roommates in the AIMERS dorm – a pairing fans have dubbed one of the cutest in the group.
He stands at 174 cm, making him one of the shorter members – but that never stops him from commanding a stage.
He is known for being particularly warm and affectionate with fans at fan sign events, making him a crowd favorite in person.
His zodiac sign, Aries, combined with his ESFP personality, makes him the group’s social butterfly and hype man during variety appearances.
🌟 Wooyoung (우영) – Vocalist, Dancer, Maknae
Wooyoung is the baby of the group, but don’t let that fool you – this maknae brings serious skills to every performance. His passion for songwriting and composing sets him apart from many K-pop youngest members, hinting at a creative future beyond just performing.
Wooyoung
- Stage Name: Wooyoung (우영)
- Birth Name: Hwang Woo-young (황우영)

- Nationality: Korean
He was the last (6th) member to be introduced, officially making him the maknae (youngest member) of AIMERS.
He was a former trainee under DSP Media and even a pre-debut member of DSP N before joining AIMERS – meaning he has more pre-debut experience than many realize.
He trained for 2 years and 6 months – longer than Seunghwan and Doryun, showing just how serious he was about debuting.
His adorable nickname is “Burdock” (우엉 / Ueong), a playful name tied to his gentle, earthy charm.
His personal hobbies include writing lyrics and composing music – proof that the creative spark in him goes way beyond performing.
He is the lightest member of AIMERS at 58 kg.
His MBTI is ENTJ – same as Yoel – which means beneath the cute maknae exterior is someone who is ambitious, decisive, and goal-oriented.
He was born on June 29, 2003, making him a Cancer ♋ – a sign associated with creativity, intuition, and deep emotional connection to others.
He and Seunghwan are dorm roommates, and fans love seeing their off-stage friendship through social media posts.
His blood type is B, and he shares this trait with his fellow Cancer, the group leader Seunghyun.
Achievements
AIMERS have built an impressive track record considering they’re still a relatively young group. Here are some of the highlights worth celebrating:
Chart Milestones. AIMERS have shown consistent chart growth since debut. Their debut single peaked at #77 on the Korean charts, but by the time they released “Starry Night” in April 2025, they had broken into the Top 15, landing at #15 – one of their highest chart peaks. Their 2024 release “Somebody” hit #23 with over 8,900 copies sold.
Japanese Market Expansion. AIMERS made a notable push into the Japanese music market in 2023, signing with Victor Entertainment for Japanese releases and hosting the AIMERS JAPAN MINI LIVE 2023 on August 26, 2023 – a significant step for any Korean act looking to build a loyal fanbase overseas.
Steady Sales Growth. Album by album, AIMERS have grown their sales numbers on the Hanteo Chart and Gaon Chart, going from 3,212 copies sold on their debut to 9,007 for “Starry Night” – nearly a 3x increase in physical sales over three years of active promotion.
Fandom Loyalty. Their fandom, Aiming, has proven to be one of the most dedicated communities among fifth-generation K-pop groups, consistently supporting chart pushes, fan voting events, and award show campaigns.
Musical Diversity. AIMERS earned praise from Korean music critics for refusing to stay in one sonic lane. From the raw energy of “Fight Inside” to the warm nostalgia of “Called Game” – filmed across beautiful Japanese landscapes – they’ve shown range that bigger groups would envy.
