D-CRUNCH — the South Korean hip-hop idol group whose name stands for “Diamond Crunch” — made a blazing impact on the K-pop scene from their debut in 2018 until their disbandment in 2022. Even now in 2026, fans from around the world still search for everything about D-CRUNCH members, their stories, and what made this boy group so special. If you’re a longtime DIANA (that’s their official fandom!) or someone just discovering their music, this is your go-to guide.
Formed under All-S Company in Seoul, South Korea and later managed by Ai Grand Korea, D-CRUNCH built their identity on raw hip-hop energy, self-written lyrics, and powerful choreography. Their core belief was simple: break through anything in your path, just like a diamond. The D-CRUNCH discography spans four mini-albums, two single albums, digital singles, and even a Japanese debut — and every release carried the fingerprints of the members themselves, who wrote, composed, and choreographed their own material.
In this article, we cover everything — the D-CRUNCH member profiles, their fun facts, the group’s biggest achievements, a full discography with music videos, and a breakdown of their live performances and tours. Let’s dive in!
D-CRUNCH (디크런치) was one of the most hardworking 4th generation K-pop boy groups of the late 2010s. Short for Diamond Crunch, the name reflects their desire to break through barriers with strong performance and powerful musicality. They were created by producer Lee Jong-seok, who is also known for producing Girl’s Day.

He is one of the co-leaders of D-CRUNCH, sharing leadership duties with Hyunwook — a rare dynamic in K-pop groups.
O.V was a founding member of the G.I.G songwriting team (Good Thing Is Good Thing) within D-CRUNCH alongside Hyunwook and Hyunoh.
He took part in the pre-debut sub-unit Geupsik-Dan, performing before the group officially launched.

His blood type is B, which fans often say matches his confident and independent personality.
He has an older sister and a younger sister — making him the middle child in his family.
O.V cited BTS as D-CRUNCH’s biggest role model, showing respect for the group that paved the way for hip-hop-focused idol acts.
He was heavily involved in crafting D-CRUNCH’s choreography, contributing creative ideas beyond just rapping.
Fans know him as the member who shapes D-CRUNCH’s overall musical direction through the G.I.G unit’s songwriting sessions.

He is a key member of the G.I.G songwriting team, helping write and compose music for the group from their very first release.
Hyunwook was part of the STOPES sub-unit (2021–2022), which debuted on January 28, 2021, with the mixtape 128√e980.
He collaborated with Chanyoung on the single “Surfing,” released on January 27, 2022.
His family includes his mother, father, and a younger sister.
Fans say that he and former member Dylan used to “live parallel lives” — they had the same classroom numbers and were both vice presidents of their student council.
His representative emoji is 🐯, a tiger, reflecting his fierce and powerful stage presence as main vocalist.
Hyunwook became an All-S Company trainee sometime between April and June 2017, one of the earlier members to begin training.
He and Dylan share a fun quirk — people who knew them said they were basically the same person in different bodies, just with different looks and names.
Despite being the main vocalist, Hyunwook was also actively involved in the group’s creative direction through G.I.G.
Hyunho (현호) — Rapper, Eldest Member
Hyunho
- Stage Name: Hyunho (현호)
- Real Name: Lee Hyunho (이현호)

- Instagram: @by_leehyunho

At 183 cm (6’0″), Hyunho is the tallest member in D-CRUNCH — and fans agree his long legs are one of his most talked-about charming points.
He was the very last member to be revealed in the D-CRUNCH lineup, announced on June 9, 2018, as the 9th member.
Hyunho jokingly said his “position” in the group was being the oldest — and he took that responsibility seriously.
He has a fun skill: he can produce smoke with his mouth, a party trick he showed off on Pops in Seoul.
Hyunho made his acting debut in the 2021 web drama Time to Be Together 1:11, where he also contributed to the OST.
He made a guest appearance in drama Voice Season 2 as a member of the fictional group NT7.
Hyunho enlisted in the mandatory military service on February 27, 2023, and was discharged on August 26, 2024.
After his discharge, he signed with BB Entertainment in 2024 and has been pursuing an acting career.
He has a younger sister, and fellow member Chanyoung once said Hyunho “takes really good care of the younger ones.”
Even though he can’t do aegyo (cute behavior) easily — unlike the maknae Jungseung — fans love him for his straightforward, cool persona.
Hyunoh (현오) — Lead Vocalist, Main Dancer
Hyunoh
- Stage Name: Hyunoh (현오)
- Real Name: Park Hyunoh (박현오)
- Birthday: March 19, 1999
- Zodiac Sign: Pisces
- Blood Type: B
- Height: 175 cm (5’8″)
- Weight: 57.1 kg (125 lbs)

Hyunoh is part of the G.I.G songwriting team alongside O.V and Hyunwook, meaning this dancer is also a creator behind D-CRUNCH’s music.
He can speak English — something fans have always appreciated and found impressive from this multi-talented performer.
Hyunoh’s family is a little different from most — he was raised by his grandmother, mother, and aunt, showing the diverse family structures that make K-pop stars relatable.
He started training at All-S Company as early as January 2017, making him one of the earliest trainees in the group.
Hyunoh was revealed on June 7, 2018, the same day as Hyunwook — a double reveal that had fans buzzing.
He’s both a lead vocalist and main dancer, one of the rare members who carries heavy responsibilities on two fronts.
Hyunoh’s blood type is B and his zodiac is Pisces — a dreamy combination that fans say matches his graceful dance style.
He’s from the same city as O.V — Changwon, South Gyeongsang Province — meaning these two share hometown roots.
During his trainee days, Hyunoh was already shaping the group’s creative identity through lyric writing and composition.
He once wore braces during D-CRUNCH’s early days — a relatable detail fans loved because it showed his genuine, down-to-earth side.

Chanyoung was the 2nd member to be revealed, announced on June 5, 2018 — just one day after the teaser campaign began.
He went to the Seoul School of Performing Arts (SOPA), where his classmates included Stray Kids’ Hyunjin and VERIVERY’s Yongseung — quite the celebrity alumni network.
Chanyoung is part of the Geupsik-Dan sub-unit, the pre-debut unit that gave him his very first taste of performing before D-CRUNCH officially launched.
Hyunwook once nicknamed him “the Vocal God has abandoned” — a teasing inside joke between members that fans still find hilarious.
He has a habit of saying the Korean word “약간” (yakgan), meaning “kind of,” very often in conversation — fans love catching it in interviews.
Chanyoung’s favorite season is fall, and he relieves stress by working out and spending time with fans.
His favorite movie is Avatar — he’s always had a love for epic, visually stunning stories.
If he could travel anywhere in the world, he’d head to Dubai or New Zealand — two very different but equally adventurous destinations.
He describes himself as a “puppy-cat” — sweet and warm like a puppy, but a little aloof and independent like a cat.
Chanyoung collaborated with Hyunwook on the 2022 single “Surfing” — a testament to his musical creativity beyond just rapping and dancing.
Jungseung (정승) — Maknae, Vocalist, Rapper
Jungseung

- Nationality: Korean
As the maknae (youngest member), Jungseung is the baby of D-CRUNCH — and fans say his cuteness is off the charts compared to the rest of the group.
His MBTI type is INTJ — the “Architect” — meaning beneath his cute maknae exterior is a deeply strategic and independent thinker.
Despite being the youngest, Jungseung stands at 180 cm (5’11”), making him one of the taller members of the group.
He was part of the Geupsik-Dan pre-debut sub-unit, performing alongside O.V, Chanyoung, and Dylan before the group’s official debut.
Jungseung enrolled in mandatory military service on January 17, 2023, and was successfully discharged on July 16, 2024.
His blood type is B and zodiac sign is Taurus — fans say the Taurus stubbornness perfectly explains his committed work ethic.
Hyunho once said that compared to Jungseung, he himself can’t do aegyo at all — a fun contrast between the oldest and youngest member.
Jungseung was also part of the STOPES sub-unit, an additional creative outlet within D-CRUNCH.
His Chinese zodiac sign is the Horse, associated with energy, ambition, and a love of freedom.
Even after D-CRUNCH’s disbandment, Jungseung’s Instagram @par_kjss remains active — fans continue to follow and support him on his solo journey.
