Doyoung

Doyoung's full name is Kim Doyoung (김도영), and he was born on December 4, 2003, in Seoul, South Korea. Because he entered the trainee system while still extremely young, much of his childhood and adolescence was spent balancing ordinary school life with professional dance and idol training.
<br • Dance was a major part of Doyoung's life before TREASURE existed. He attended Def Dance Skool, a well-known dance academy in Seoul that has trained numerous aspiring K-pop performers, before successfully entering YG Entertainment.
<br • Doyoung reportedly joined YG Entertainment in 2015, meaning he was only around 11 years old when he became a trainee. By the time TREASURE finally debuted in 2020, he had already spent roughly five years preparing within the company.
<br • Fans actually saw Doyoung on television before YG Treasure Box. In 2017, he appeared alongside other YG trainees during the YG-versus-JYP trainee battle on Mnet's Stray Kids, when the two companies' trainees competed through performances.
<br • That pre-debut YG team also included future TREASURE members, meaning some of the relationships within TREASURE began years before the group officially existed.
<br • Doyoung competed as part of Treasure B on YG Treasure Box. Unlike contestants who had recently entered YG, he already had several years of training behind him and was particularly recognized for his dance ability.
<br • He wasn't selected for the first seven-member TREASURE lineup after the survival show. Instead, Doyoung was later announced as a member of MAGNUM, the second group YG planned to debut from the show's contestants.
<br • Doyoung therefore went from YG trainee to MAGNUM member before ultimately becoming a TREASURE member. When YG reorganized its plans, TREASURE and MAGNUM were combined, eventually producing the larger group that debuted in August 2020.
<br • He is one of TREASURE's members most strongly associated with dance. His years of training before debut gave him a particularly polished foundation, and performance has remained one of the clearest ways he distinguishes himself within the group.
<br • Doyoung has described dancing as something that can change his mood. Rather than approaching choreography purely as a professional obligation, dance has been part of his life since childhood and remains closely connected to how he expresses himself.
<br • He has participated in creating choreography, showing an interest in the construction of performances rather than simply memorizing choreography prepared for him. This creative interest complements TREASURE's increasing member involvement in songwriting and performance production.
<br • Doyoung is famous among fans for his unexpectedly smooth—and sometimes hilariously dramatic—flirting. He regularly delivers affectionate comments or cheesy lines with complete confidence, which has become one of his most recognizable personality traits in fan interactions.
<br • His confidence with romantic-sounding comments contrasts with his relatively soft and cheerful image. Doyoung can switch from being playful and cute to delivering an unexpectedly serious compliment, often leaving the other TREASURE members laughing or embarrassed on his behalf.
<br • He frequently expresses affection toward TREASURE's fans, TREASURE MAKERS, or TEUMEs. Doyoung tends to communicate his appreciation openly rather than maintaining a distant or mysterious idol persona.
<br • Doyoung's representative animal is commonly associated with a rabbit. His bright expressions and softer facial features helped the comparison stick, and rabbit imagery is frequently used by fans when representing him.
<br • He enjoys fashion and putting together outfits, another interest he shares with several TREASURE members. His offstage styling often reflects a cleaner and more youthful aesthetic than Hyunsuk's more experimental streetwear-heavy approach.
<br • Doyoung has shown an interest in basketball and other physical activities. Given his dance background, he tends to perform well in movement-based challenges and competitive games featured in TREASURE's variety content.
<br • He attended Apgujeong High School before later studying at the School of Performing Arts Seoul (SOPA). His education overlapped with his years as a trainee and eventually with TREASURE's early career.
<br • Doyoung graduated from SOPA in 2022, reaching the milestone after already debuting as a professional idol. Like several younger TREASURE members, he experienced the unusual situation of attending high school while simultaneously promoting with an internationally active K-pop group.
<br • He participated in TREASURE's web drama The Mysterious Class. The supernatural school drama allowed Doyoung and the other members to practice scripted acting and portray fictional characters instead of simply appearing as themselves.
<br • Doyoung is known for being optimistic and encouraging toward the people around him. His comments frequently emphasize enjoying the present and maintaining a positive outlook, which fits the upbeat personality fans see in TREASURE's behind-the-scenes content.
<br • He debuted after spending nearly half of his childhood within the trainee system. Considering that he entered YG at around 11 and debuted at 16, Doyoung's path demonstrates just how young some K-pop trainees begin preparing for careers that may not materialize until years later.
<br • His transformation is especially noticeable when comparing his early YG appearances with modern TREASURE performances. Fans can effectively watch him progress from a small child performing in trainee evaluations to an experienced dancer performing in arenas and domes.
<br • Despite being one of TREASURE's younger members, Doyoung actually has one of the group's longer histories with YG Entertainment. His age can make him seem like one of the later additions, but he was already training at the company years before several members joined.
