Seok Matthew
Canadian-Korean performer, compact dance engine, bright vocal color, and the member who can turn three seconds into the part everybody quotes.
Early life and training
Matthew was raised in Vancouver and trained in Canada before entering the Korean idol system. He studied at the same dance academy associated with Sung Han-bin, and their pre-show connection became part of the emotional shorthand viewers recognized on Boys Planet.
Growing up in Canada shaped more than his English fluency. He moves easily between cultural registers in interviews, understands when a joke needs translating instead of merely repeating, and often becomes a bridge during overseas promotions. That skill is work, even when fans only notice that the conversation flowed.
Boys Planet: how he reached the lineup
Matthew entered Boys Planet as an MNH Entertainment trainee. Early evaluations established him as a capable dancer and stable performer, while his friendship with Han-bin gave the program a ready-made relationship viewers could follow. The challenge was proving that he was more than the cheerful friend in somebody else’s storyline.
He finished third. His final placement reflected a fanbase drawn to the contrast between his sunny offstage personality and the sharper, more confident performer who appears when music starts.
Career with ZEROBASEONE
Seok Matthew debuted with ZEROBASEONE on July 10, 2023 through Youth in the Shade and “In Bloom.” The original nine-member run moved quickly: multiple million-selling releases, Korean and Japanese promotions, award shows, tours, brand work, and a fandom that always knew the project clock was running.
In ZEROBASEONE, Matthew became one of the group’s strongest English-language communicators and a reliable source of “killing parts”—short lines or gestures designed to remain after the chorus ends. He also grew into darker and more mature concepts without losing the rhythmic snap that made his bright-era performances memorable.
When the original term ended in 2026, Matthew remained in the continuing five-member ZEROBASEONE with Sung Han-bin, Kim Ji-woong, Kim Tae-rae, and Park Gun-wook. Their first mini album in that formation, Ascend-, deliberately moved toward contemporary R&B, groovy hip-hop, and a more mature performance style.
Skills, voice, and stage identity
Matthew dances with a low center of gravity and quick directional changes. His size makes compact movement read especially sharply because there is little wasted space. Vocally, his tone is bright and slightly nasal in a way that cuts through dense production; producers can use one line from him to wake up a section.
What to watch
- Accent lines: he often gets the phrase meant to become the quote or meme.
- Footwork: his lower-body control keeps quick choreography grounded.
- Expression changes: he can switch from playful to direct inside one camera pass.
Era map
- “In Bloom”: the bright debut image and the pressure of arriving with a built-in ending.
- “CRUSH” and “Feel the POP”: heavier performance work followed by playful summer-pop precision.
- “GOOD SO BAD” and “BLUE”: stronger vocal identity and more confident camera work.
- “LOVEPOCALYPSE”: the emotional closing stretch of the original nine-member chapter.
- “TOP 5”: the first clean introduction to the five-member era. He delivers the repeated hook differently each time, keeping a minimal groove from settling into one mood.
Fandom file
Matthew’s best-known fandom image is sunshine with bite. Fans enjoy his directness, Canadian English moments, and the gap between his friendly conversational energy and the confidence of his dance breaks. The useful archive includes his pre-debut dance work, Boys Planet stages, bilingual interviews, and how his performance style changed across eras.
The important line between useful fandom detail and nonsense is evidence. Nicknames, habits, and inside jokes belong here when they are traceable to broadcasts, interviews, or the member himself—not because a random graphic with seven fonts repeated them.
Current chapter
Matthew openly loves second-generation K-pop, so the early-2000s R&B and dance-pop framing of “TOP 5” fits him unusually well. He described the concept as his moment, and the performance supports that: the styling, groove, and close-range camera work let him look cool without overexplaining himself.
