Who is Choi Woojin?
Choi Woojin competed on Boys Planet after nearly two years of training and lasted through episode eight. He entered the show with a stated goal of ranking third, which is both specific and slightly funny. Not first. Third. A man with realistic seating preferences.
Woojin’s hobbies include cycling and taking photographs with a digital camera. Photography is also his specialty, and he has said spring and snowy winter are his favorite seasons to shoot. When he feels low, he looks at the sky and gets lost for a while. That is either emotional self-regulation or the opening scene of a very quiet music video.
Onstage, Woojin gives TIOT a compact, quick-moving center option. His dance habit of shaking his head could easily become messy, but it often adds texture to parts that need release rather than another perfectly squared shoulder. He names Rain as a role model and likes D.O.’s “That’s Okay,” which fits the softer side of his taste.
His motto says anything can be done if you try it one hundred times. K-pop training probably tested whether he meant that literally. He appears to have survived the experiment.
Woojin also functions as one of the group’s visual documentarians. A member who pays attention to framing tends to understand where a camera is looking, and that awareness shows when he shifts from group formation into close-up without suddenly performing at a different emotional volume.
Boys Planet and the Redstart team
Woojin entered Mnet’s Boys Planet as a Redstart ENM trainee alongside Kim Minseoung, Kum Junhyeon and Hong Keonhee. He finished in 50th place. That ranking did not put him near the final project group, but it kept the four trainees visible as a company team rather than scattering their stories across unrelated post-show projects.
Redstart used that continuity. The trainees held fan meetings under the phrase “This Time Is Our Turn,” announced the name TIOT in August 2023 and began a long pre-debut period together. Woojin therefore had time to adjust from survival-show evaluation to repeatable group performance before the official five-member debut.
Frame the Blueprint: the pre-debut year
TIOT released Frame the Blueprint: Prelude to Possibilities on August 28, 2023. The project’s lead track, “Unbeatable,” reworked Click-B’s 2001 song into a younger hip-hop performance. The title and song choice made the post-survival-show message obvious without pretending that elimination had never happened.
The four-member pre-debut period included music-show stages, fan events and the songs “This Is Our Time,” “BUNGEE,” “Surfing” and “Starlight.” For Woojin, the period supplied the repetition his own motto describes: cameras, formations and vocals practiced across an actual promotional cycle rather than only inside a training room.
Kick-START and the official five-member debut
Shin Yechan joined before TIOT’s official debut on April 22, 2024 with the EP Kick-START and title track “Rock Thang.” The Korea Times described the release as a new adventure after eight months of pre-debut activity. The album also included “Goosebumps,” presented as a confidence-boosting track, and “Moonrise,” framed as a healing song.
Woojin’s position is best understood in that expanded lineup. His compact movement and camera awareness help bridge the larger personalities around him, while the vocal arrangements can use his lighter tone without asking it to carry every climax. The page should not inflate that supporting work into a solo career: no separate formal solo catalog has been verified, so he belongs on the Member shelf rather than the Artist carousel.
Performance development and the photography eye
Woojin’s interest in digital photography is relevant because idol work is relentlessly framed. He notices lines, timing and where attention sits inside an image. Onstage, that awareness appears in how he changes intensity when a formation becomes a close-up without making the transition look like a different performance.
The head movement noted in his dance habits can add looseness to otherwise square choreography, but control determines whether it reads as texture or noise. TIOT’s pre-debut year gave him an unusually public laboratory for learning that difference before the official debut clock started.
