Siyeon QWER (Lee Si-yeon)

Who is Siyeon (QWER)?

Lee Siyeon, professionally known as Siyeon, serves as the main vocalist and rhythm guitarist of the South Korean girl band QWER. Born on May 16, 2000, she represents the fourth and final member added to the band's lineup. Her stage name Siyeon is commonly abbreviated to the nickname Siyomin among fans and fellow members.

Siyeon holds historic significance as the first Korean member of the Japanese idol group NMB48 and the second Korean individual overall to join the broader AKB48 Group. Her path to QWER followed a two-year tenure with NMB48 Team M, which she joined in August 2021 after passing auditions for the group's 7.5th Generation. She achieved notable recognition during this period, placing 2nd in the AKB48 Group singing competition and appearing on multiple Japanese variety programs as a foreign idol.

Before her Japanese idol career, Siyeon participated in K-Pop training and performed as a member of the dance team Napul Naful, which conducted busking performances on the streets of Hongdae from 2018 to 2019. She initially pursued opportunities in Japan after feeling uncertain about prospects in the Korean market. However, financial constraints led to her graduation from NMB48 on August 8, 2023, as the group's payment structure left less popular members without sustainable income and prohibited secondary employment.

Within weeks of her NMB48 graduation, Siyeon received a casting call from QWER in late August 2023. She officially joined the band as their main vocalist on August 15, 2023, and made her debut with QWER on October 18, 2023, through the single "Harmony from Discord". Her musical capabilities extend beyond vocals to include guitar performance, songwriting, and composition contributions to the band's repertoire.

Siyeon's early life and path to becoming an idol

Growing up with dreams of the stage

Since elementary school, Siyeon experienced an unexplained motivation to become an idol, drawn to music and singing with aspirations of stage performance. This ambition existed paradoxically alongside severe stage fright that prevented her from delivering class presentations or singing before audiences. Her daily routine during this period involved extended computer gaming sessions in her room. During her second or third year of high school, she joined a Korean agency to prepare for a K-pop debut. She attended Gangil High School and received vocal training at a music academy.

Busking days with Napulnapul

Between 2018 and 2019, Siyeon performed with the dance team Napulnapul, which conducted street busking of idol songs and dances in Hongdae, Seoul. The group operated during her final year of high school, providing practical performance experience that contrasted with her earlier stage anxiety.

The decision to pursue Japan

Siyeon gained admission to an arts university but sustained an ankle fracture before classes commenced, requiring crutches and forcing a year-long leave of absence on account of the institution's distance. During this break, she signed with an entertainment agency, dropped out of university, and became a trainee. After her scheduled Korean debut was cancelled in 2020, she felt stagnant watching peers pursue university education. She abandoned her Korean idol aspirations and decided to study in Japan, supported by her strong Japanese language proficiency. After acceptance into a Japanese university, she encountered an audition announcement for NMB48, a group she had followed for years. She submitted her application primarily as a casual attempt, anticipating rejection.

Siyeon's journey with NMB48

Joining NMB48 as the first Korean member

Siyeon initially auditioned for NMB48's 7th generation in January 2020, passing the second round but unable to attend the third round final audition owing to COVID-19 pandemic travel restrictions that prevented her from entering Japan. In March 2021, she received an email from NMB48's entertainment company offering an additional audition opportunity for the group's 7.5th Generation. After successfully passing this June 2021 audition, she joined NMB48 as an official trainee in August, entering as a Kenkyuusei (research student) on August 14, 2021. This trainee-like position preceded her placement in Team BII Kenkyuusei Team in February 2022, followed by promotion to Team M on July 16, 2022.

Achievements and challenges in Japan

After her Team M promotion, Siyeon found it difficult to shine among more senior members despite notable accomplishments. She placed 2nd in the AKB48 Group singing competition. However, she received severe backlash from Korean netizens in June 2023 over a gravure photobook. The Japanese idol salary structure presented additional obstacles, as compensation was not fixed and paid monthly. As a less popular member, she was not making enough money to sustain herself and was prohibited from taking a second job.

The difficult decision to graduate

Financial constraints ultimately led to her graduation announcement on June 30, 2023. She held her final theater performance and graduation ceremony on August 8, 2023, concluding her two-year tenure with the group.

How Siyeon became part of QWER

Following her NMB48 graduation, producer Kim Gyeran traveled to Japan specifically to recruit the final member for QWER. The band concept, inspired by anime series such as K-On! and Bocchi the Rock!, required a four-member lineup consisting of vocalist, guitar, bass, and drums. With the bass, guitar, and drummer positions already filled through earlier recruitment efforts, only the vocalist role remained vacant.

During this period, Siyeon was contemplating her future career direction when she received the casting call from QWER. Kim Gyeran had identified Siyeon through Instagram Live interactions and subsequent direct message exchanges. The producer then visited Osaka City to meet with her in person and extend the formal invitation. Siyeon's initial reaction to the offer was skepticism, as she did not believe the opportunity was genuine and suspected it might be a joke.

Despite her disbelief, she accepted the position as main vocalist and rhythm guitarist, marking her return to the Korean entertainment industry. Her professional idol experience from NMB48 made her the only QWER member with prior established performance credentials, while her fellow members came from backgrounds as Twitch streamers and content creators. The recruitment occurred within days of her graduation, with some sources indicating the offer came just five days after her emotional final performance. She formally announced her membership on August 15, 2023.
