Billlie's Tsuki Reveals She Cut Contact With Parents for 6 Months to Learn Korean

Billlie member Tsuki has captured hearts with a deeply personal revelation about the extraordinary lengths she went to in order to master the Korean language — including cutting off all contact with her parents for six months when she was just 12 years old.

The Japanese-born idol shared her story during the March 6 broadcast of MBC's popular variety show I Live Alone, where she gave viewers an intimate look at her daily life in Korea, now in her tenth year living in the country and her second year of living independently.

A 12-Year-Old's Determination

Tsuki revealed that when she first arrived in Korea as a young trainee, she made a bold and unconventional decision to accelerate her language learning. She deliberately chose to completely isolate herself from her native Japanese language environment, going as far as stopping all communication with her family back home.

During the show, she explained her method with striking clarity. She memorized 30 Korean vocabulary words every single day and tested herself rigorously on each one. The self-imposed discipline was remarkable for someone so young, and the dedication behind her approach spoke volumes about her commitment to her dream of becoming a K-pop idol.

The Emotional Reunion

After approximately six months of this intense immersion strategy, Tsuki reached a turning point. She found herself comfortable enough to hold everyday conversations in Korean, and it was at that moment she finally reached out to her parents again. The reunion, though not detailed extensively on the show, marked the successful completion of a grueling personal challenge.

Her method clearly paid off. Today, Tsuki is widely recognized for her impressive Korean language skills, frequently impressing hosts and fellow guests on variety show appearances with her natural fluency and quick wit in Korean.

Life as an Independent Idol

On I Live Alone, Tsuki also shared glimpses of her current daily routine. Now living on her own, she starts her mornings with light exercise before settling into her ongoing Korean language studies. Her unique approach involves watching Korean films and pausing them to look up unfamiliar words, a technique she has maintained even after years of fluency.

The dedication Tsuki showed as a 12-year-old trainee continues to define her approach to personal growth. Her story resonated deeply with viewers, many of whom praised her determination and emotional strength on social media following the broadcast.

Billlie, which debuted in October 2021 under Mystic Story, consists of seven members including Moon Sua, Suhyeon, Haram, Tsuki, Siyoon, Haruna, and Sheon. The group has been steadily building their presence in the K-pop scene, with Tsuki emerging as a standout personality through her variety show appearances.
