2. The E’last U Member Profiles (2026)

👥 Member Overview Table

---

🌟 CHOI IN (최인) — Leader, Dancer, Vocalist

Choi In grew up in Daegu, South Korea — a city famous for its food and fashion culture.

He is one of the biggest fans of K-pop legends like BTS’s Jimin, EXO’s Kai, SHINee’s Taemin, and NCT’s Taeyong — basically his idol lineup is a who’s who of legendary K-pop performers.

He serves as the Leader of E’last U, which means he’s the one keeping everyone grounded and on track during practices and promotions.

Choi In is known for his smooth and precise dance moves — his dancing style leans sharp and controlled.

He enlisted for mandatory military service on September 2, 2024, and his discharge was expected around March 1, 2026, making his return a major moment for fans.

He was put on a promotional hiatus in September 2023 for personal reasons before his enlistment.

Choi In has a blood type of AB — which in Korean pop culture is often associated with creative, unpredictable personalities.

He carries the Aquarius sign, which fans say matches his independent and creative spirit perfectly.

He participated in writing and composing songs for E’LAST — showing he’s not just a performer but a true artist.

His hometown of Daegu is also the hometown of many other famous Korean stars, giving Choi In solid company in the celebrity hometown club.

🌟 ROMIN (로민) — Main Vocalist, Dancer

Romin is an only child — so all that charisma and talent wasn’t split with a sibling!

He has a serious passion for fashion — styling is one of his go-to hobbies, and it clearly shows in his visuals.

His role models are some of the biggest names in music: Justin Bieber, NCT 127 (especially Taeyong), BTS, and NCT Dream.

Romin can speak a little English — which he actually mentioned in his self-written profile, making it even more endearing.

His individual fanbase goes by the name “Rominist” — and if you become a fan of his, welcome to the club.

He hates dried fruit (except bananas) and summer heat — basically he and summer are not best friends.

When it comes to food, Romin loves beef, pork, chicken, noodles, hamburgers (specifically Burger King), and pizza (Papa John’s) — the man has very specific fast-food loyalty.

His hobbies include watching Marvel movies, playing games, traveling, shopping, and playing soccer.

Romin sang the OST “Starlight” for the drama So I Married The Anti-Fan, which was released on June 4, 2021 — showing off his solo vocal talent.

His MBTI is ISTP — the quiet, observational type who surprises everyone with unexpected wit and skill.

🌟 WONJUN (원준) — Main Rapper, Vocalist, Maknae

Wonjun is a former contestant on Produce X 101, where he ranked 47th — so he came into E’last U already knowing the pressure of the stage.

He can speak Chinese and English in addition to Korean — making him one of the group’s most multilingual members.

As the maknae (youngest member) of E’last U, Wonjun has the youngest energy of the group but is no less talented than his older bandmates.

He was previously the host of the EBS children’s show “Boni Hani” — which actually caused him to miss E’LAST’s Awake comeback promotions due to scheduling conflicts.

Wonhyuk and Wonjun held a fan meeting together on August 14, 2019, even before their official group debut — showing just how much they valued connecting with fans early on.

Wonjun loves socializing and making new friends — by all accounts, he’s the kind of person who lights up a room.

He’s a total fashionista — style is clearly a priority for him, both on and off stage.

Wonjun participated in writing and composing songs for E’LAST’s debut album Day Dream, proving he’s been creatively involved from day one.

He’s known for having a warm and friendly personality that makes him a fan favorite both within the group and among ELRING.

His Pisces energy is said to come through in his emotional, expressive rap delivery — fans always say he puts real feeling into his performances.
