Early Life and Education:

Jaehyuk's family is from Yongin, where he grew up with his parents and an older brother who was born in 1997. He had big dreams from a young age. As a toddler, he wanted to be a businessman, which is why his followers call him "Baby CEO." But fate had other intentions, and an unplanned street casting led him to the spotlight.
He started his education at Shinri Elementary School and then went on to Hongcheon Middle School. He went to Yongin Hongcheon High School for high school, then moved to Kwangsung (or Gwangseong) High School, where he graduated. Jaehyuk showed his love for the performing arts by temporarily attending Baekseok Arts University and concentrating in Practical Dance. But in the end, he quit so he could focus on being a trainee and getting ready for his debut with YG Entertainment. This choice shows how dedicated he is to music, putting hard work and training ahead of school.

Background and Training:

Jaehyuk's story about how he got into the K-pop business is like a fairy tale. He was the only TREASURE member to be found through street casting. YG scouts contacted him directly after school one day, and he joined the label just a few months before the survival show YG Treasure Box premiered in late 2018. His raw skill didn't go ignored; prominent agencies like SM, JYP, CUBE, Woollim, Pledis, and Yuehua all wanted him, showing that he had star quality from the start.
Jaehyuk trained with YG for almost three years, starting with six months. He became a left-handed all-arounder, excelling in singing, dancing, and even sprinting. He showed off his rhythmic skills by singing Sik-K's "Ring Ring" in his introduction video. Jaehyuk was heartbroken as he was kicked off of YG Treasure Box, a tough competition that made TREASURE, on episode 9. But his hard work paid off; he was brought back for the finale, which secured his place in the original seven-member lineup of TREASURE. Later, the group grew to ten members when it merged with the Magnum unit and Ha Yoon-bin left. Jaehyuk is a practicing Catholic who gets strength from his faith. He often shows his love for his groupmates freely, and he is known for saying "I love you" the most often. His pastimes, such reading webtoons, watching cookery videos, playing games, and listening to music, provide us a peek into how he spends his free time like a normal young person.

Career with TREASURE:

TREASURE's debut on August 7, 2020, with the single album The First Step: Chapter One, which had the hit song "Boy," made Jaehyuk's career take off. He was a sub-vocalist, lead dancer, and sub-rapper (with a "Pearl" emoji) for the group. He helped them become very popular, and their first four albums sold over a million copies in five months, which was the fastest for a YG rookie group. The whole album The First Step: Treasure Effect (January 2021) reached the top of the Circle Album Chart. Their Japanese debut was just as successful, selling 57,000 copies and reaching number one on Oricon.
The "Second Step" era (2022–2023) was a time of big changes. Chapter One (February 2022) with "Jikjin" won TREASURE's first music program on program Champion and got 20 million views on YouTube in just a few days. The B-side song "Darari" became a hit on TikTok (500 million views) and topped charts all over the world. "Hello," which was certified gold in Japan, was in Chapter Two (October 2022). Jaehyuk joined the inaugural Asia "Hello" tour (2022–2023), gathering 420,000 fans across 10 countries, and a Japan fan meeting tour surpassing 500,000 attendance, including a historic Tokyo Dome show—the first for a Korean performer.
The "Reboot" project with Columbia Records in 2023 helped them reach more people around the world. Jaehyuk made his debut with the sub-unit T5, which stands for "flower boy quintet" and includes Jihoon, Junkyu, himself, Doyoung, and So Jung-hwan. They released the pre-single "Move" in July 2023. In just two days, the album Reboot sold 1.7 million copies. "Bona Bona" peaked at No. 27 on the Circle Digital Chart and charted in the UK. The "Reboot" tour brought in 300,000 people in Japan alone from 2023 to 2024. The Black Clover OST "Here I Stand" (No. 1 on the Billboard Japan Hot 100, platinum-certified) and the digital single "King Kong" (May 2024) were two of the best. There was also the Japanese single "King Kong / Reverse" (August 2024) for the TV show Densetsu no Atama Sho. There were 170,000 fans at the Wonderland Japan fan convention in July and August 2024. As of January 1, 2025, TREASURE's leadership changed. Junkyu and Asahi took over for Choi Hyun-suk and Jihoon. Jaehyuk was in the pre-release "Last Night" (December 2024) and the third EP "Pleasure" (March 7, 2025), which was led by "Yellow." The trio announced the "Special Moment" fan concert tour, which would take them to Seoul (March 28–30), four U.S. cities (April, ~2,500 attendance weekly), and ten nights in four Japanese cities (April–May, 150,000 fans altogether), ending with a live broadcast from Saitama Super Arena. Jaehyuk teased "LOVE PULSE" events on Weverse in September 2025, hinting at future comebacks. The "PULSE ON" tour will stop in 14 cities in Asia from 2025 to 2026. In an interview in April 2025, the band talked about how Pleasure is about collective growth and healing music. As of October 2025, TREASURE is still a 10-member group, even though everyone has their own plans.

Jaehyuk's net worth 2025:

It's hard to guess how much K-pop stars like Jaehyuk are worth because they keep their finances private and YG shares group revenue. However, because TREASURE is becoming more and more successful— with multi-platinum albums, sold-out tours with more than a million fans, and partnerships around the world— Jaehyuk's net worth is expected to be between $3 and $4 million USD by 2025. And it shows money made from music sales (like Reboot's 1.7 million copies), endorsements, and tours that bring in tens of millions of dollars. YG made 11.2 billion KRW in net income in 2025, which helps members earn more money through royalties and bonuses. Jaehyuk's work with his sub-unit and viral songs like "Darari" probably help him get more streams on Spotify and YouTube.

Notable Songs and Contributions:

Jaehyuk is a sub-vocalist and lead dancer for TREASURE. His warm voice and enthusiastic delivery add to the group's music, and he often shines in high notes and ad-libs. He doesn't write most of the lyrics, but his fun personality makes the group work better together. He also makes playlists like "Midnight Stroll," which has introspective songs like The Black Skirts' "Everything" and TREASURE hits. Key contributions are important lines in happy anthems and sad ballads.

"Boy" (2020): The First Step: Chapter One's first single. Jaehyuk's lively singing gives the song its youthful energy, which is why it became platinum.
From Chapter Two: "I Love You" (2020). His sweet lines are a reflection of who he is, and 27K Genius notes point out the bits that fans love the most.
"MMM" (2020): An upbeat song where Jaehyuk's dancing break really stands out when they perform live.
"My Treasure" (2021): The title of Chapter Three. Includes his smooth ad-libs in the chorus.
"Jikjin" (2022): The Second Step: Chapter One lead; Jaehyuk's rap-vocal swap won them their first award.
"Darari" (2022): A viral B-side with 500 million views on TikTok. Its smooth bridge makes its hook even more catchy.
"Hello" (2022): The title of Chapter Two; Jaehyuk's warm voice goes well with the lyrics about greetings.
"Move" (2023): A T5 sub-unit release before Reboot. He danced with his unit mates to show off his skills.
"Bona Bona" (2023): Jaehyuk's beautiful verses bring back the "flower boy" feeling, and the song peaked at the top of global charts.
"King Kong" (2024): Digital single; his strong speech suits the bold topic.
"Yellow" (2025): The lead song from "Pleasure," it features upbeat vocals that show how much the band has grown since their March comeback.

Jaehyuk's rise from being an underdog on a survival program to a tour powerhouse solidifies his role in TREASURE's "healing" sound, as he said in interviews in 2021 and 2025: putting care for each other first despite busy schedules. His journey will have more unforgettable moments with the "PULSE ON" tour in 2025 and a possible full album in the summer.
