2015–2020: Debut with CLC and acting debut

 

On March 13, 2015, Cube Entertainment released the profile information and images of Yujin, as the fourth member of CLC following Yeeun, Sorn, and Seungyeon, through their official social media. In Cube's words: Choi Yu-jin, who has all the visual elements to be called a 'heavenly idol', aims to become the strongest idol's 'proportioner' with an unusual physical condition. She was introduced as a vocalist and dancer of the group and can cross various genres such as belly dance, popping, rocking, and house dance with a high understanding and expressiveness of dance performance. Along with member Seungyeon, she is considered to be one of CLC's 'top two dancers'. Yujin and fellow CLC members were also chosen as the new model for a Korea's clothing brand, SMART Uniform, alongside Got7 and B1A4.

Yujin made her debut as a member of CLC on May 19, 2015, with the release of the single "Pepe" off the five-track EP First Love, of which all the proceeds were donated to children with developmental disabilities.

On August 17, 2015, she joined the cast of Real Man for the third season's female soldier special as the youngest member among the ten entertainers including rapper Jessi, Japanese broadcaster Sayuri Fujita and former national tennis player Jeon Mi-ra. She gained wider recognition after joining the show, where she drew attention over her small face and slender body frame, measuring 162 cm and 42 kg, taking first place in push-ups despite her skinny arms that couldn't even measure blood pressure. Later, she went viral with the caption "Choi Yu-jin's 3-stage transformation into a female soldier" from a 'pretty and fresh girl' to a 'dignified baby soldier' for which she received the nickname "Baby Soldier" and "Patriotic Idol" from soldiers of the Armed Forces and viewers of the show. Yujin's appearance on the show ended in late September 2015. At the end of the year, Yujin shared a stage with cast member Jessi and Kim Hyun-sook performing S.E.S' "I'm Your Girl" at the 2015 MBC Entertainment Awards.
