With flawless technique and razor-sharp precision, Lee Know is the embodiment of control and charisma on stage. As the dance leader of Stray Kids — a title given to him by Bang Chan himself — he anchors the group’s powerful choreography with elegance and accuracy. A core member of the subunit DanceRacha, Lee Know’s style is defined by clean lines, perfect form, and an unwavering sense of rhythm — no surprise for someone who completed JYP Entertainment’s entire dance course in just two weeks, the fastest on record. Before joining JYPE on July 15, 2017, he was already a professional dancer, and that experience shows in every step he takes.

But Lee Know is far more than just a dancer. He boasts an impressive vocal range, often showcasing his signature falsettos, and has been dubbed the group’s “Unreachable Visual” since debut. His sculpted features — sharp, cat-like eyes, a high nose bridge, and refined expressions — have made him a standout favorite among fans for his striking presence. Yet beneath the statuesque beauty lies one of the group’s quirkiest and most endearing personalities.

Affectionately called a “weirdo” by his fellow members, Lee Know is known for his savage wit, dry humor, and quick reflexes, making him as entertaining off stage as he is captivating on it. Despite his cool or aloof exterior — the classic tsundere — he’s the second oldest in the group and is often referred to by STAYs as the “mom” of Stray Kids, helping Bang Chan care for the younger members. A devoted cook, he frequently prepares meals for the team, quietly expressing affection through acts of service.

In June 2025, Lee Know was officially appointed Global Brand Ambassador for Gucci. This appointment highlights how his sculptural visuals, polished stage presence, and innate sense of style align seamlessly with Gucci’s heritage and modern direction.

A proud cat dad, Lee Know treasures his three cats; Soonie, Doongie and Dori— who live with his parents — and often features them in his vlogs. His connection with cats isn’t just literal; fans often say he embodies one himself: independent, graceful, mysterious, yet secretly soft-hearted.
