Billlie’s Tsuki stole the show as a guest student on JTBC’s hit program 'Knowing Foreign Language High School'. Airing on February 18th KST, Tsuki brought her infectious energy and dazzling variety show talents to captivate viewers.

Right from her entrance, Tsuki radiated her signature "human vitamin" charm, setting the stage with her lively personality and upbeat responses.

A memorable highlight was Tsuki's delightful banter with the show's hosts. While engaging in a light-hearted conversation with her teacher Boom, she effortlessly balanced respect towards her senior, (G)I-DLE’s Minnie, resulting in a comedic dynamic. The humor peaked during the class president nominations, as Tsuki hilariously exposed Jonathan's charming antics in their bid for a permanent guest spot, showcasing their close bond and comedic rapport.

Revealing the secret to her impeccable Korean proficiency, Tsuki disclosed, “I moved to Korea at the age of 13. My determination to enhance my Korean led me to even cut off communication with my mom for a few months.” The cast members lauded her commitment and innovative learning techniques.

In a vocabulary test segment aimed at evaluating leadership qualities, Tsuki’s interpretation of the phrase “Let’s do it verbally” as “Don’t say it, just act” provoked laughter from the entire studio.

At the same time, Billlie is making waves globally as they embark on their highly anticipated world tour 'Billlie World Tour ‘Our FLOWERLD (Belllie’ve You)’ ASIA & OCEANIA', commencing with a spectacular show in Melbourne, Australia, on February 19th (local time).
