From debut stories to fun facts, D1CE discography, career achievements, and live performances — we cover it all. And if you’ve ever wondered about the D1CE 2026 legacy and where each member stands today, you’re in the right place.

D1CE (stylized in all caps, Korean: 디원스, pronounced “D-Once”) was a South Korean boy band formed under Happy Face Entertainment (later rebranded under D1CE Entertainment, a subsidiary of Dreamcatcher Company). The group consisted of five immensely talented members: Jo Yong Geun, Kim Hyun Soo, Jung Yoo Jun, Park Woo Dam, and Woo Jin Young. They officially debuted on August 1, 2019, with their first mini album Wake Up: Roll the World, and became known for their blend of K-pop, ballad, and hip-hop styles.

What made D1CE special? Every single member had competed in major Korean idol survival shows — including Produce 101 Season 2, MIXNINE, and Boys24 — before finding their home together. That battle-tested experience gave D1CE a stage presence and emotional depth that fans immediately recognized. Their official fandom name, Don1y, was revealed on February 16, 2020 — 200 days after their debut — cementing a deeply personal bond between the group and their supporters.

While D1CE officially disbanded on January 20, 2023, following the expiration of all five members’ exclusive contracts with D1CE Entertainment, their music, their legacy, and their individual journeys continue to inspire fans in 2026 and beyond.

Let’s get into everything you need to know about D1CE and their five extraordinary members.

2. Kim Hyun Soo (김현수) — Hyunsoo

Kim Hyun Soo is D1CE’s powerhouse vocalist — the member whose husky, unique voice instantly sets him apart. Born on April 12, 1995, in Daegu, South Korea, his southern Korean background gives him a distinctive dialect that fans absolutely adore.

His hometown is Daegu, which gives him a very recognizable regional accent that fans find incredibly endearing.

Kim Hyun Soo is famous within the fandom for his dad jokes — he loves to make everyone laugh with terrible puns.

Before D1CE debuted, he released a special mini album called Present with fellow member Woo Jin Young in June 2018.

He ranked 14th on MIXNINE out of hundreds of contestants — one of the highest-ranked future D1CE members on the show.

He and Woo Jin Young recorded their collaborative EP Present with the song “Falling in Love” — a tropical summer track with a music video featuring Dreamcatcher’s Yoohyeon.

His husky vocal tone is considered one of the most distinctive in all of K-pop — fans say you can identify him in under three seconds.

He holds the record for the most unique pre-debut path in D1CE: Boys24 → Woollim trainee → Happy Face trainee → D1CE debut.

Woo Jin Young is D1CE’s main rapper and the youngest member (maknae), born on May 31, 1997. Don’t let his youngest-member status fool you — this guy has been grinding in the industry longer than most. He competed on Produce 101, dominated MIXNINE by ranking 1st, made his solo debut, and brought the most rapper energy to D1CE’s sound.

Woo Jin Young ranked 1st on MIXNINE — he literally won the competition, though the planned group debut was canceled due to failed contract negotiations.

His nickname “Loco” came from his time as a JYP Entertainment trainee, because he looked like the famous Korean rapper Loco.

Another memorable nickname is “Charmander” — thanks to a resemblance to the beloved Pokémon character that fans latched onto immediately.

He has an older brother who is 8 years his senior — a large age gap that shaped his maturity despite being the group’s youngest.

He absolutely hates cucumbers — a very specific food aversion that fans never let him forget at fan signs and events.
