Career Overview :
Seo Youkyung, known by her stage name Youkyung, debuted in August 2012 as the drummer for the K-pop girl group AOA under FNC Entertainment. She was unique as the only member who participated solely in the band sub-unit AOA Black, making her the “half-angel” in AOA’s “7+1” concept.
Youkyung remained an active member of AOA Black, contributing to their band-focused performances such as the debut sub-unit single “Moya” in July 2013, and the band version of “Get Out” from the Wanna Be album in 2016. However, on October 15, 2016, her exclusive contract with FNC Entertainment ended, effectively leaving the group although she remained listed as a guest member for any future band activities.
Following her departure, Youkyung shifted her focus to education and music. She enrolled in Yewon Arts University and graduated in 2018 with a degree in Practical Music. Around May 2018, she began teaching drums and producing drum tabs, while maintaining a YouTube channel (“You’s Drum”) where she regularly uploads drum covers — including performances of AOA Black’s “Come See Me.”
In 2020, Youkyung co-founded a drum-centric duo, Y&Z PROJECT, alongside Zune Drummer, and they debuted with the single album BOOT THE SYSTEM on June 1, 2020. That same year, she released her own solo mini-album “CONNECT” on October 19, 2020.
Continuing her band journey, in late 2022 Youkyung joined the three-member band UNI as their drummer, culminating in their debut single “Dive” released in December 2022. Throughout this phase, she has remained active in both live performance, music education, and her strong presence as an independent musician.
Personal Life & Interests :
Youkyung is known for her calm and thoughtful personality, often focusing her energy on music, education, and personal growth rather than the spotlight. After leaving AOA, she pursued a degree in Practical Music at Yewon Arts University, which reinforced her dedication to her craft.
Outside of her professional drumming, Youkyung enjoys teaching, sharing drum tutorials, and connecting with fans through her YouTube channel. She’s passionate about rhythm, music production, and collaborating with other musicians through independent projects like Y&Z Project and UNI.
She lives a relatively low-key lifestyle, preferring creative expression and self-development over flashy entertainment. Youkyung is also known for being humble, supportive of her peers, and committed to her path as a dedicated musician.
Youkyung enjoys a calm, creative lifestyle and prefers meaningful, small-scale projects over high-profile media appearances. She’s also an advocate for independent musicianship and often shares drum tutorials and insights with fans and students alike.
Net Worth :
As of 2025, Youkyung’s estimated net worth is approximately **$1 million**, according to some sources. Other estimates suggest a possible range between **$1 million and $5 million**, derived from her career as AOA’s drummer, her musical education, band projects, teaching, and content creation via her YouTube channel.
These figures remain unofficial and speculative, as Korean idol finances are typically private and not independently verified.
